Cold Bed on Route news & patch notes

Update v3.26 is now live.

This update addresses the following two points:

1. Fixed a bug where actions in the Side Story wouldn't execute properly, causing the game to softlock.

In our previous v3.25 update in early March, we added a control guide image. Because it was a minor update, we let our guard down and failed to run a comprehensive check on the whole system.

As it turns out, the Unity version had changed during that process. This caused some object assignments to unbind, which meant taking specific actions in the Side Story would fail to execute properly, preventing further game progress.

We sincerely apologize for the inconvenience. If you were unable to complete the Side Story in v3.25 due to this issue, please give it another try with this v3.26 update.

2. Added hint dialogue to the final battle of the Side Story.

While fixing the bug above, we realized that the gameplay itself might still feel a bit confusing (a "what am I even supposed to do?" kind of situation). To help follow up on this, we’ve added some hint dialogue.

That said, it's not something you'll see under normal circumstances. It triggers after losing the final battle two or more times, replacing the standard defeat dialogue. Each subsequent loss will reveal a new hint, cycling through a loop that returns to the standard defeat dialogue on the fifth loss.

Additionally, we have made minor text adjustments throughout the game.

We have officially added Linux support in v3.25, specifically with Steam Deck users in mind.

Please note that because I currently do not have a native Linux environment for testing, this support is being released in an experimental state. I cannot guarantee it is fully optimized or bug-free at this stage. If you encounter any issues, I would greatly appreciate it if you could report them in this thread: https://steamcommunity.com/app/3250010/discussions/0/598530063829318431

UI Update: Mouse Icons

I previously removed the mouse icons from the top-right control guide because they didn't look quite right. However, I realized that without them, it might not be clear that mouse controls are supported. I have decided to bring them back starting with v3.25.

Note for Windows Users:

I am currently experiencing an upload error with the Windows version. I will push the update for Windows as soon as the issue is resolved.

Cold Bed on Route has been updated to v3.24.

When upgrading the artbook to the 7th edition, we noticed several typographical errors and have corrected them.

There are no changes to the actual content.

The artbook has been officially updated to the 7th edition.

To commemorate reaching 10,000 copies across all platforms, a special illustration previously posted on Twitter and the blog has been added.

This illustration is not placed in Chapter 2, but has been added to Chapter 6, Section 1.

You can check the edition number on the colophon on the final page of the artbook.

If your edition is outdated, please try deleting the Artbook folder from your local files, then verify the game files to re-download it.

Cold Bed on Route is updated to v3.23.

Cold Bed on Route has been updated to v3.22.

This update only includes typo corrections and translation adjustments, with no content changes.

Update details:

• Revised wording in the MEMO screen instructions

• Overall improvements to the English translation of the MEMO screen

Cold Bed on Route is updated to v3.20

The version number may seem a bit jumpy because this update follows the mobile version rollout.

By the way, the mobile version is also progressing with updates — the Google Play version has already been updated, and the iOS version is currently under review.

This update includes the following changes:

Bug Fixes

• Fixed a bug where, on the BAG screen after planet descent, moving a resource different from the one selected with the arrows caused the originally selected resource to become unselectable again.

• Fixed a bug where selecting a resource inside a container on the BAG screen and moving it caused the container itself to become unselectable.

• Fixed a bug where, during actions after arriving on a planet, the HP change indicator circle only properly animated on the first change, with subsequent changes happening instantly.

• Fixed an issue on the MEMO screen where the outer frame of the table of contents did not change color according to the current time.

UI Improvements

• Adjusted letter spacing for long resource names on the ITEM screen.

• On the BAG screen, made it possible to transfer selected resources to the pilot or girl with drag-and-drop even with a small horizontal movement.

• Removed the mouse icon from control instructions during mouse/keyboard operation due to its poor appearance.

Others

• Minor display and behavior tweaks.

It’s taken quite some time since the release, but with today’s update to version 3.17, all the originally planned system-side updates have now been completed.

Here are the major changes since the initial release:

Support for Keyboard and Gamepad Controls

The main story is now playable using three control schemes: mouse, keyboard, or gamepad—as well as combinations of these.

For the side stories, due to the nature of movement and throwing mechanics, control is limited to mouse (+ keyboard) or gamepad.

We understand that keyboard and gamepad controls may not feel entirely intuitive or smooth in some parts.

Current control mappings are displayed in the top-right corner of the screen (or top-left on the exit screen, due to layout constraints).

Windowed Mode Support and Improved Behavior When Inactive

From the start screen, selecting the third option from the top on the right will cycle through preset window sizes. After selecting a size, restarting the game using the visible button will apply the change.

We also addressed an issue where background music playback could behave strangely when the game window became inactive and then active again.

Improved Visual Feedback for Mouse Controls

We've added visual hover effects when using the mouse—such as buttons enlarging or changing color when hovered.

Several UI elements that were previously unchanged from the mobile version—such as the width of the ITEM screen or the positioning of the MEMO screen index—have also been adjusted for better visibility and usability on PC.

Side Story Balance Adjustments

In the final stage of the side story, we made the following changes to improve playability:

Increased the impact strength of thrown objects

Extended the time limit

Adjusted hit detection for some elements (improved or reduced as appropriate, based on visual appearance)

Bug Fixes

Multiple bugs have been identified and resolved in this update.

Revised Artbook

The in-game reference materials have been updated to Version 6.

Key changes include:

Adjustment of the initial bind value in section 6.2 “Battle” final stage (from 1 → 2)

Clarification added to the knockback value explanation (values are based on stage width = 1)

Minor layout tweaks throughout the section

With this update, system-related development is now considered complete.

However, bug fixes will continue to be addressed, so if you encounter any issues, please feel free to report them in the relevant thread.

Cold Bed on Route has been updated to version 3.17

With this update, gamepad support has now been fully implemented across the main story and the side stories. This marks the completion of functional updates for the time being.

Feature Additions

• Added keyboard/gamepad controls to the side stories. In the side stories, keyboard-only input is not available; you can choose between mouse-only (as before), keyboard + mouse, or gamepad-only controls.

Bug Fixes

• Fixed an issue where the UI would not properly switch when toggling between keyboard and controller input on the post-landing screen.

• Fixed a programming issue where extended gameplay could cause input lag with gamepad controls due to accumulating processes.

• Fixed an issue where trying to select a flower in reverse order (← key or left button) on the start screen without any prior selection would result in abnormal behavior.

UI Adjustments

• Added a mouse icon to the keyboard control guide (no changes to the text description).

• Adjusted the input display so that it now updates properly when using the left mouse click during gamepad input mode.

• Modified system panel buttons (Exit/Return to Title) to be usable with C, Space, Enter, or the confirm button on a gamepad. The same applies to the DLC display and side story lamp display panels.

• During gamepad use, common actions mapped to multiple buttons are now shown in the lower-right corner of the MEMO screen.

• Updated the tutorial display to reflect the corresponding gamepad buttons when using a gamepad.

• Made several minor textual corrections.

Cold Bed on Route has been updated to version 3.16!

This update mainly adds support for game controllers.

The control display will automatically switch to controller inputs when a button is pressed on the controller. Please refer to that for guidance on how to operate the game.

That said, the controls may feel a bit—or quite—awkward at the moment. Additionally, the manual and tutorial have not yet been updated to reflect controller support.

Some buttons have shared functions beyond what is displayed on-screen. These are as follows:

• A (Cross) = B (Circle) = RT = LT

• L = Y (Square)

• R = X (Triangle) = Select

We plan to gradually include explanations and support for these in future updates.

Note: Controller support for the side stories (gaiden) is not yet complete.

Other Updates:

New Features

• Added controller support to the main story

Bug Fixes

• Fixed an issue where pressing Q or E on the start screen without selecting anything caused abnormal behavior

• Fixed an issue where pressing Space or Return on the start screen triggered unintended actions

• Fixed a bug where choosing an action before picking up the serum after landing on the planet could cause abnormal behavior

• Fixed an issue where, after planetfall, having only one item across all bags would prevent re-selection when switching tabs and returning

UI Adjustments

• Adjusted the transparency of key inputs that are not usable on the planet surface

Cold Bed on Route Version 3.15 Update

Apologies — we missed a bug in the previous update where having certain items upon landing on a planet could cause the game to behave incorrectly. This has now been fixed. We’re truly sorry for the serious bug that could prevent progression. Details below:

Bug Fixes

• Fixed an issue where the game could become unplayable if the player landed on a planet while carrying certain items.

Specification Changes

• Previously, if you lit the lamp in the main story and then switched to a side story, the presence of a chair in the main story could also prevent progress in the side story. This behavior has been changed so that side stories can now proceed regardless of the main story’s state.

UI Adjustments

• Adjusted keyboard control display on the side story start screen and the ITEM screen.

• Adjusted the positions of some flowers.

Thank you for playing.

Cold Bed on Route has been updated to version 3.14! A nicely rounded version number.

Here are the details of the update:

New Features

• The main game can now be fully operated using only the keyboard. The supported keys are: arrow keys (or W/A/S/D), C, Q, E, and Z (used only to call the exit panel). Keyboard controls are currently available only in the main story.

Bug Fixes

• Fixed an issue where some lines on the start screen and map screen were getting cut off.

• During planetary actions, when HP was between 0.0 < HP < 0.005, it used to display as 0.0. It will now correctly display as 0.1.

UI Adjustments

• Keyboard operation hints now appear in the top-right corner on most controllable screens.

• (On the clear result screen, they appear in the top-left due to layout constraints.)

• On the ITEM screen, item slots were becoming too wide on larger screens. Now, their maximum width is limited to the height.

• In screens like LOG, when an item has a very long name, it used to overlap with nearby UI elements. Now such names are truncated, e.g., “Extremely Long Item Name” becomes “Extremely Long It…”.

• On the MEMO screen, the table of contents was overlapping with the main content. It has been shifted slightly to the left.

• On the BAG screen, the window space between the pilot and the girl has been widened.

• On the BAG screen, when hovering over an item and it enlarges, the edges of the icon are no longer cut off.

• Adjusted color highlighting for 6-action selections on the Route screen.

• On the Trail screen, graph axis numbers were hard to see in white, so they have been changed to black.

• Made a few tweaks to the opening illustration.

Other

• Improved responsiveness and usability of the BAG screen.

At last, keyboard-only controls are now available!

That said, the keyboard operation might feel a bit clunky at times. This feature is more of a stepping stone toward full controller support, so we still recommend combining it with mouse controls for a better experience.

Also, several UI elements such as ITEM, MEMO, and BAG hadn’t been properly optimized for wide PC screen layouts.

• We’ve made the following minor adjustments:

• ITEM: Prevented item slots from becoming excessively wide.

• MEMO: Used some of the empty space to improve layout.

• BAG: Slightly extended the screen width horizontally.

Cold Bed on Route has been updated to version 3.13.

Although version 3.12 was considered a stable release and we initially planned to focus on adding features like keyboard controls, this update primarily addresses an issue found in v3.12. Additionally, some specifications have been changed.

Specification Changes

• The "Use" button at the bottom center of the ITEM screen and the "Move" button on the MAP screen now require a long press instead of a single click.

• By "long press," we mean a brief 0.5-second hold, similar to the duration required for discarding items.

Bug Fixes

• Fixed an issue where the "Close" button in the bottom-right corner of event conversations was not being displayed.

Note on Input Changes These two actions—"Use" and "Move"—are critical for decision-making. To prevent accidental presses, we have changed their activation to require a slight (0.5-second) long press.

Cold Bed on Route has been updated to v3.12.

Here are the details:

New Features

• Windowed Mode Added. You can now switch between fullscreen and windowed mode. This option is the third item from the top on the right side of the start screen. Each press toggles the display mode, and selecting “Restart” from the displayed panel will restart the game and apply the new screen size.

Balance & Gameplay Changes

• When playing as a character other than the "Girl" in the side story, the stamp attack (a red circle appears and you dash into enemies again) will no longer be triggered after a dash attack. The tutorial text has also been updated accordingly.

UI Tweaks & Bug Fixes

• Fixed an issue where players could perform a dash attack on enemies that had already been defeated and were falling in the side story mode.

• Disabled VSync to prevent graphical issues (such as abnormal drawing speed) reported by players using high refresh rate monitors.

About the VSync Change:

Some users with high refresh rate monitors reported abnormal rendering behavior (possibly due to the game running too fast). To address this, we’ve turned off VSync.

However, we currently do not have access to a high refresh rate monitor for testing, so this fix is based on our best assumptions.

If the issue still persists, we’re very sorry — please report it again so we can investigate further.

About the New Windowed Mode:

We've also implemented windowed mode support in this update.

Please note: changing the screen mode does not take effect immediately upon button press.

After selecting the windowed/fullscreen toggle, you'll need to click “Restart” on the displayed panel to apply the change and restart the game.

A Small Note from the Developer:

It took a while to implement windowed mode, and to be honest, I hadn’t anticipated this feature request at all — mainly because I always play in fullscreen mode myself.

That said, thinking about it now... it’s true that most games allow toggling between fullscreen and windowed mode.

I had a realization: “Oh right, most games do support that... the game industry is more polished than I thought!”

Cold Bed on Route has been updated to version 3.11.

The details of the update are as follows:

Bug Fixes & UI Adjustments

• Fixed a bug where, if a container with supplies had its DR reduced to 0 on a planet and its contents were scattered as DROPs, attempting to collect them from the BAG screen would cause abnormal behavior.

• Fixed an issue where mouse hover did not work correctly for containers in the BAG screen when hovering over item names on a planet.

• Fixed a bug where background music would overlap when returning to the title screen via the system button in the bottom left corner.

• Adjusted button highlight colors and border thickness throughout the UI.

While not a frequently occurring issue, the handling of container destruction on planets — which could potentially lead to progression-blocking bugs — has now been properly addressed.

When a container is destroyed, its contents are scattered in the surrounding area. However, during this process, a variable meant to track "which box (if any) an item is in" was not being processed correctly. As a result, the system would try to reference something that no longer existed, leading to errors.

This type of bug, when triggered, would interrupt subsequent processing. As a result, items could be duplicated or even replaced with "nothingness." We sincerely apologize for the inconvenience this may have caused.

Cold Bed on Route has been updated to version 3.10.

The update includes the following changes:

Balance Adjustments

• In the Gaiden (side story), the cooldown time before gaining an additional throwable use has been reduced from 4 seconds to 3 seconds.

• The mechanic in the Gaiden where getting hit by a knockback attack would reduce your throwable count by 1 and reset the cooldown has been removed. (The related tutorial message in Stage 4 has also been updated.)

• The hit detection for dangerous red attacks in the Gaiden has been reduced by about 5–10% without changing their visual appearance. (If your character is barely overlapping with the attack visually, it will now likely not count as a hit.)

• The hitbox size of the final battle gimmick in the Gaiden has been increased by 1.5 times.

Bug Fixes & UI Improvements

• Fixed an issue where keyboard input prompts were not being displayed on the title screen while in Gaiden mode; they are now shown properly.

• Slightly improved processing behavior on the title screen.

• Fixed an issue where the flower selection in Gaiden mode showed barely any color change when using keyboard input.

• Changed the timing of throwable count consumption in the Gaiden: it is now consumed at the start of a throw instead of after it finishes.

• Fixed a bug in the Gaiden’s "VS Goat" fight where the head movement (nodding) animation would not play to completion.

This update mainly focuses on balancing adjustments in the extra content.

In short: throws are easier to perform, harder to lose, attacks are easier to dodge, and gimmicks are easier to hit.

Compared to the previous update that increased stun durations, each individual change may seem minor, but together they subtly make the game easier to clear.

Cold Bed on Route has been updated to version 3.09.

The update includes the following changes:

Balance Adjustments

In the final battle against the Dog-Wolf, the restraint value when hitting with a thrown item or similar has been increased from 1 → 2.

(The restraint now lasts until the enemy takes two actions.)

UI Tweaks & Bug Fixes

• Adjusted the timing of certain sound effects.

• All actions on the start screen can now be performed using the keyboard.

• Added a keyboard control guide to the upper-right corner of the start screen.

• Adjusted the flower positions and hitboxes on the start screen to make Alstroemeria and Pomegranate easier to tap, as they were overlapping with other elements.

While several UI tweaks were made, the primary focus of this update is the balance adjustment in the final battle with Between Dog & Wolf.

There are three levels of difficulty in understanding the gimmick of the Dog & Wolf’s final battle:

Cold Bed on Route is updated into v3.08.

• Fixed a bug where, upon starting a second or third playthrough after transferring items in and out of containers, the contents of the containers would incorrectly remain in the same state as the previous loop, disrupting gameplay.

This update focuses solely on addressing this relatively severe bug.

We apologize, but if your save data was created in v3.07 or earlier, the affected loop may still have corrupted item states—even if the default values have been reset.

To restore proper functionality, you can either delete the current playthrough from the start options or complete a loop (even if it results in a game over), which will reset the state correctly.

Since this update is brief, we’d like to take the opportunity to explain the bug in more detail:

Each item in the game (whether it’s a girl, a ship, or a metal box) is stored as a single unified data block. This includes data such as weight, durability, and status (e.g., acquired, not acquired, stored in a box, discarded, etc.).

Containers like a metal boxe have an additional structure: inventory data that holds information on what items are stored inside.

When beginning a new loop (either by clearing the game or deleting data from the title screen), these item data blocks are reset by copying values from a predefined set of "initial state data."

However, the issue in this update arose because the inventory data of container items was mistakenly copied using shallow copy instead of the intended deep copy.

To clarify:

A deep copy (the correct behavior) duplicates the initial state data into the container’s inventory data, creating an entirely separate instance—no problems here.

But with a shallow copy (the incorrect behavior), the container's inventory data ends up referencing the same object as the initial data. This means that any interaction—such as adding or removing items during gameplay—would also modify the supposedly immutable initial state data.

As a result, if you continue playing without restarting the game, changes to the container contents directly affect the initial state data. Then, if you begin another loop, the game copies this now-corrupted “initial” data back into the new playthrough—effectively carrying over container contents from the previous loop, which should not happen.

This issue was difficult to reproduce consistently because the likelihood of it occurring increased with each additional loop. Our initial assumption that it would trigger in the second loop caused us to overlook cases where it only appeared later.

Cold Bed on Route has been updated to v3.07.

The main changes include (likely) fixes for button overlap issues on ultra-wide displays and improvements related to BGM behavior.

Update Details:

• Fixed an issue where the arrow buttons on the bottom tabs would sometimes overlap with other buttons on ultra-wide displays.

• Fixed a bug where the BGM would disappear after switching away from the game screen while it was playing, and then returning.

• Increased the scroll speed of the action option bonuses display (affected by status or items) during planetary actions by 10x, which was unintentionally left unchanged in the previous update.

• Fixed a slight delay that could occur in the start of audio during the opening scene after the intro jingle and tutorial end.

• Changed how the DLC materials collection is recognized: recognition now occurs when pressing the DLC button, not at game start.

Regarding BGM behavior:

Normal operation of ship interior BGM after BGM-related events (including the backlog) ends is as follows:

Full volume loop once

-> 20% volume loop once

-> Switches to ambient sounds

On planets, BGM plays for one loop before transitioning to ambient sounds. It will resume in the morning.

About DLC:

The system has been modified so that DLC recognition can now occur at any time, not just at game start.

However, whether DLC downloads during gameplay depends on how Steam handles it. Therefore, we can't guarantee that purchasing the materials collection during gameplay will make it immediately accessible.

Currently, there are still a few bugs and areas we'd like to improve. Notably, a major remaining issue involves processing errors when carrying certain containers (mainly beds?) across loops. We aim to address this as soon as possible.

The update to version 3.06 has been released. The main changes focus on improving comfort and usability, particularly regarding mouse hover behavior and center mouse wheel scrolling.

Update Details:

• Made mouse hover effects on buttons more noticeable.

• Increased scroll speed by 20x when using the center mouse wheel on tabs such as the Items tab to improve ease of use.

• Fixed a bug where switching to the Items tab immediately after returning to the Conversation tab (without any active conversation events) would cause the Conversation tab’s image to remain.

• Fixed an issue where music set to loop only once and lower in volume was not functioning as intended.

• Adjusted the ambient sound volume when no background music is playing.

• Fixed a bug where initializing the route (returning to the starting point) from the start screen while on a planet would cause abnormal behavior.

• Split some lengthy dialogue text that was overflowing from speech bubbles.

• Extended the delay before the cut-in skill activates during the final battle with the Wolfdog from 60 seconds to 120 seconds.

Another update will be released soon, as there are still issues that need to be fixed.

We’ve released update v3.05.

The changes are as follows:

-In ship interiors, on planets, and during event dialogues, we have added on-screen prompts indicating that you can flip pages left and right using the A and D keys.

(The left and right arrow keys also still work as before.)

Due to undesirable behavior caused by using the spacebar for button operations, we’ve changed these operations to use the C key instead.

Specifically, the following changes were made from v3.04 → v3.05:

• Start Screen: Hold Space to start → Hold C to start

• Ship Interior / Dialogue Screen: Hold Space to propose HEX action → Hold C to propose HEX action

• Ship Interior / Map Screen: Press Space to navigate → Press C to navigate

• Planet / Route Screen: Press Space to initiate combat → Press C to initiate combat

• Ending Screen: Hold Space to exit → Hold C to exit

For all other controls, please refer to the previous update article titled “Departure.” -When the current cargo weight is less than 0.1 WG but greater than 0.0 WG, the UI would display it as 0.0 WG, which felt unnatural.

This has now been fixed so that any value under 0.1 WG is always displayed as 0.1 WG. -In Dog &Wolf, once the girl’s name has been revealed in the story, her name will now be displayed consistently thereafter. Additionally, we are aware of a known issue where if there is no ongoing conversation and you switch away from the “Conversation” tab inside the ship, the tab may not properly disappear.

We haven’t fully isolated the cause yet, but we now have a better sense of when this issue occurs, and we hope to fix it in the next update.

"Cold Bed on Route" Steam Release Now Available! The initial release version is v3.04. You can check the version at the bottom-right corner of the title screen.

A DLC art book is also available. This is the 5th edition, and the edition number is listed on the colophon (final page) of the book.

The original title of Cold Bed on Route is 霜夜ゆく (Soya Yuku).

🔹 Upcoming Plans

For the foreseeable future, we are planning the following updates and adjustments:

\

↑

Bug fixes

UI adjustments

Balance adjustments for Between Dog & Wolf

Mobile version update

Controller support

\

🔹 Bug Reports

We've created a \ thread in the Community Discussions section. Posting your reports there will help us notice them more quickly. You can write in either Japanese or English.

Although it's labeled as a bug report thread, if you find anything that's confusing in the UI or difficult to control, we consider those as practical bugs as well. Please feel free to report such issues in the same thread.

🔹Known Bugs

The following bugs are present as of version v3.04:

Music and jingles may occasionally play slightly later than expected.

→ This is scheduled to be adjusted.

Progress does not occur even though the displayed weight or remaining time shows as 0.0.

→ It appears that internal values between 0.05 and 0.00 are being rounded and displayed as 0.0. While the system is supposed to round up in these cases, it isn’t working correctly. We will adjust it so that as long as the internal value is still positive, it will display as 0.1.

🔹 About Sales

Although the Steam Summer Sale will begin soon after the release, this title will not be discounted during that event.

This is because the Release Sale (10% off) will already be ongoing during the Summer Sale period. The release discount will remain in effect for that duration.

Future sales may occur irregularly under the following circumstances, but please note that they are not guaranteed—we tend to forget:

During major sales other than the 2025 Summer Sale, especially when there's a fun or fitting date

Around the release of a new game or port

When participating in special events

🔹 Keyboard Controls

While only mouse controls are explained in-game as the primary method, we’ve experimentally added keyboard controls as well.

This is part of preliminary testing in preparation for controller support. Therefore, keyboard controls are currently not documented in the game and do not cover all mouse-based operations—they are supplemental only.

As of v3.04, the following keyboard inputs are supported:

This article serves as an announcement that the equation-based adventure game "Cold Bed on Route" will be released on Steam on June 21. It also aims to explain what kind of game this is for first-time players, and how it differs from the mobile version for those who have already played it.

For First-Time Players

This game is an equation-based, roguelite, sci-fi adventure inspired by Tom Godwin’s The Cold Equations. It was first released for iOS in 2021 and later made available on both iOS and Android in 2022. The Steam version is a port of those mobile editions for PC.

The basic gameplay revolves around managing resources while trying to uncover the game’s various endings. Each playthrough tends to be short, and although failure is part of the experience, what you learn carries over to future runs—so feel free to experiment in different ways.

While the story takes initial inspiration from The Cold Equations, as mentioned above, the gameplay system was strongly influenced by Kaichō, the winner of the 5th “Punge” (a free game contest for 3-minute games of Japan)—or at least, that’s what we believe.

For Those Who’ve Already Played the Mobile Version

The core gameplay—where and how you acquire resources, the different endings, and the conditions required to reach them—remains unchanged from the mobile version.

Here are the main updates and differences:

• New Bonus Content "Between the Dog and the Wolf" is included. After lighting the lamp, you can switch to this content from the upper-right corner of the start screen. It’s a very short (10–15 minutes) side story, separate from the main game.

• Adjusted layout for PC’s widescreen aspect ratio. The main information is still centered, but certain screens now display additional information on the sides.

• Background music in ship mode now loops twice. It plays normally at first, then at half volume, followed by ambient sound.

• BGM is now in stereo on the PC version. The mobile version had all sound recorded in mono due to file size constraints, but PC allows for larger file sizes, so BGM is upgraded accordingly.

• A rare save corruption bug seen on mobile (occasionally) has likely been fixed. The problem was assumed to be caused by overly redundant save data not processing in time, so we simplified the save handling and ensured it completes properly.

• If you’ve purchased the bonus materials DLC on Steam, you can now open it from within the game. It doesn’t open inside the game interface, but rather launches your PDF viewer directly.

• The English translation has been significantly revised from the ground up. Though the translation is still amateur work, it’s hopefully improved to some extent.

• Other minor tweaks have been made throughout. While most won’t be visibly noticeable, if anything feels off, feel free to leave a comment somewhere—it might be fixable.

Lastly, the Steam version (v3.X.X) will eventually be updated to the mobile versions as well. While some aspects, like widescreen support, may not carry over, the "Between the Dog and the Wolf" content will be available on mobile in the future. That’s all for now. Details about future updates will be announced in a post-launch article.
