🦌 Hello, Deer Heroes!
We have just released an update featuring command adjustments for certain skills, as well as various bug and typo fixes.
We have updated the input command for Gleam’s skill, "Heal," as follows:
Before: ↑ + Mana Weapon
After: ↑ ↑ Mana Weapon
Reason for the Change: The "Heal" skill comes with a significant drawback: you lose your weapon upon use. With the previous simple command, players often triggered the skill accidentally. We took the feedback seriously that "learning the skill itself could become a disadvantage (risk) for the player" due to these accidental activations. By changing the command, we have ensured that players only trigger the skill when they explicitly intend to.
To ensure a smoother gameplay experience, we have implemented the following fixes:
Stage Name Corrections: Fixed typos and missing characters in several stage names.
Display Bug Fix: Resolved an issue where existing skill commands would disappear from the list after acquiring Gram’s additional skills.
That’s all for this update! If you encounter any bugs or have any suggestions, please let us know in the community hub.
Deer is Life! DEER-CHAOS! 🦌✨
Hello, fellow Deer!
A minor update has been applied to the Deer Hero Soundtrack.

🦌 Hello, Deer Heroes!
This time, we’ve released a small update for the global ranking system— something some players care deeply about, while others completely ignore (or so we hear)!
In the global rank displayed on the save slot selection screen, you can now see the score difference between you and the next higher-ranked player.
That’s all for this update!
If you find any bugs or have requests, feel free to let us know in the community.
Deer are made for battle!
Deer Chaos! 🦌✨

🦌 Hello, Deer!
We’ve released an update for the Heaven content.
Fixed an issue where certain skills could not be obtained even when the time requirements were met.
Fixed some incorrect text in messages.
The time requirements for obtaining skills in Tower-kun were higher than originally intended, so they have been adjusted.

🦌 Hello, Deer Heroes!
We’re excited to announce that the “Heaven” update for Deer Hero has officially launched!
The game is also participating in the Steam Spring Sale 2026. If you haven’t become a deer yet, now is the perfect time to jump in at a great price!
Here are the details of the update:
“Heaven” is an extra stage available only to players who have cleared all main game stages. Here, the strongest warriors await, far surpassing the bosses from the main story.
After completing the main story, players can select the Heaven stages from the map screen to start their challenge.
The tale that unfolds between the main game and Heaven (not told in-game):
After finishing everything, Ererere is visited by his teacher. "If you want to aim even higher, there’s a place I can recommend."
Curious and with some free time, Ererere decides to visit this place. As they leave, the teacher quietly mutters: "Don’t die..."
After overcoming a perilous path and climbing seemingly endless stairs, Ererere finally arrives at Heaven—a town that appears peaceful at first glance. However, a powerful aura fills the area, radiating strength that surpasses any enemy faced before.
One of the inhabitants speaks to Ererere: "A newcomer… You seem capable, but can you survive here? In Heaven, you either fight and win, or sit in the corner and lick salt…"
Thus begins Ererere’s new, intense battle.
10 New Bosses Includes both reimagined bosses and brand-new ones. Over 100 stages in total when combined with the main game!
3 New Mana Weapons Combine old and new weapons to overcome powerful bosses.
New Skills Two new skills have been added.
New Techniques for Existing Mana Weapons Unlock multiple new abilities by meeting specific conditions.
\
Heaven clear status is now reflected in rankings
Added Steam achievements
\
Dash will no longer activate while holding the down key
Endings can now be fast-forwarded with the attack button
\ (Minor)
Tonfa Spin: Charge speed slightly decreased
Energy Rapier: Charge speed slightly increased
Rage gauge gain has been slightly rebalanced (wider difference between low and mid damage gain)

🦌 Hello, Deer everyone!
We’ve released a new update that adds features in preparation for the upcoming Heaven Update.
This feature is experimental and was added as a test for the Heaven update. It may be adjusted or improved in future updates.
An active connection to the Steam servers is required for it to function correctly.
From the title screen, go to \ → \. On the right side, you can view various scores along with your global ranking.
Each score is calculated based on the total clear time and Great Time across all stages.
If you play using multiple save files, only your best score will be reflected.
If your ranking cannot be retrieved, nothing will be displayed.
Only players who save the game after this update will be counted in the rankings.
That’s all for now! If you discover any bugs or have requests, please report them via the community.
The Heaven update is still in active development!
Deer Chaos! 🦌✨
🦌 Hello, Deer Heroes!
It’s time for some Deer Hero news.
Here is the current development status of the large update “Heaven”:
Overall progress: approx. 50%
Breakdown by category:
Programming: 40%
Graphics: 70%
BGM: 100% (Complete!)
Development is progressing smoothly overall, but as more ideas and details we want to polish keep coming up, we are considering splitting the update into multiple releases instead of a single drop.
We asked the residents of Heaven, “What exactly is Heaven?” Here’s what we’ve learned so far:
“Heaven” is not an afterlife, but a settlement near the realm of the gods, a place only the strongest can reach.
The Heaven update will focus purely on defeating the bosses that reside there.
There will be some new Mana Weapons and Skills.
However, they won’t completely outperform existing strong equipment — they are meant for situational use and variety.
Bosses can be challenged in any order.
There will be no no-damage bonus (we think players have had more than enough of that in the main game).
The content will mainly focus on defeating enemies. Time-based rewards might exist.
That’s all.
Deer Chaos! 🦌
Hello, Deer Heroes!
This time, we’ve released an update that adds several new features.
Turning this on in the settings will make you game over in one hit! It might be handy when going for No Damage Great bonuses.
You can now shorten the dash input window across five levels. If you often dash by accident, try setting it shorter.
After clearing all stages, the total clear time will be shown on the save data selection screen. The same applies if you cleared all stages with Great rankings. Use it as your business card as a true Deer Master!
That’s all for now!
The Heaven update is still in development! If you encounter any issues or have feedback, please feel free to share it in the community.
Deer Chaos! 🦌✨
🦌 Hello, dear Deer Heroes!
We’ve discovered that one track was missing from the soundtrack, so we’ve released an update!
🎵 Soundtrack Update: Missing Track Added
The following track has been added: 17. Amidst the Fluctuation – Underworld
That’s all! We’re sorry for the missing track — thank you for your patience.
Deerchaos! 🦌✨
🦌 Hello, fellow Deer!
It’s time for some Deer Hero news.
The Deer Hero Original Soundtrack is now on sale!
A bundle containing both the game and the soundtrack is also available. Even if you already own the game, you can still purchase the soundtrack at the bundle discount — so it’s the better deal!
And one more thing — new tracks will be added in the future as part of the “Heaven” update! Of course, anyone who purchases the soundtrack now will receive the additional tracks later as a free update.
That’s all for now.
Shikaos! 🦌✨
That’s all.

🦌 Hello, Deer Heroes!
It’s time for some news about Deer Hero!
We’re hard at work on the next update, but we also have a few other announcements to share.
By popular request, the Deer Hero soundtrack is finally coming out!!
The store page is now live, so check it out for release dates and details.
The release will be scheduled soon, as soon as the tracks are approved!
If you're interested, please add it to your wishlist!
Along with standard MP3s, it includes high-quality WAV files — even higher quality than the in-game BGM. If you want to feel the chaos while working or commuting, this is the perfect soundtrack to grab!
Many players have uploaded superplay videos of Deer Hero, but there weren’t any beginner-friendly ones. So we made a video showing the “Day 1” stages, including the recommended order and key points. If you want to breeze through the early game, be sure to check it out!
We’ve also launched the store page for Deer Legend, a related title to Deer Hero.
Unlike Deer Hero, which is action-focused, this game features exploration-based, high-speed, chaotic action RPG gameplay with growth elements.
Since we are prioritizing updates for Deer Hero, the release is still a ways off. If you’re interested, please add it to your watchlist! We also welcome your feedback in the community.
We’re currently about 20% done. Some bosses and additional BGM have been completed, and we’re now working on implementing the system features.
That’s all.
Deer Chaos! 🦌

Hello, dear Deer Heroes!
This time, we’ve implemented an update with bug fixes and balance adjustments.
Fixed an issue where the Iron Ball skill could be obtained without meeting the required Time Attack conditions.
We have adjusted the damage balance on some stages:
Reduced the damage of certain multi-hit attacks that made it too easy to take continuous hits.
Increased the damage of special/major attacks to make them more rewarding.
\
Magician Gorozo I - III
Tower-kun's Request II
That’s all for now! If you find any other bugs or issues, please feel free to report them in the community.

🦌 Hello, fellow Deer!
It’s time for some Deer Hero news!
🎬 【RTA Challenge】
A brand-new Deer Hero RTA (speedrun) video has been posted!
This refined route clears the stages with minimal skills and weapons, relying purely on player skill and smart strategy — a must-watch for fans of high-level play. (Please note: the linked video contains spoilers up to the end of the main stages!)
There are several Deer Hero RTAs out there, but this one currently holds the fastest time.
The runner, Run, is a legendary deer who achieved feats such as “All Stages Great” just days after release.
Thank you for the incredible gameplay! (Video shared with the creator’s permission.)
The first major update, “Heaven”, is currently in development!
This will be a special mode composed solely of boss battles — and the first boss is now complete!
Here’s a little sneak peek of the screen… though it still looks like a “nochi,” doesn’t it?
Balancing has proven quite tricky, so we’re taking our time to make sure it feels just right.
Stay tuned for more updates!
Deerchaos！🦌✨
Hello, dear Deer Heroes!

🦌 Hello, Deer Heroes!
We have some exciting news about the upcoming update for Deer Hero!
We’re currently developing our first major update: “Heaven.”
This is an endgame expansion designed for those who have completed the main story — a new challenge that awaits players who have conquered every stage!
In Heaven, powerful foes stand before you. Defeat them all and claim the throne! 👑
This update will feature boss battles only, each with unique new enemies. Development has just begun, and since every boss is being created from scratch, it may take some time — but we’ll share more details as progress continues.
Stay tuned, and embrace the chaos!
🦌 Deer CHAOS!
Hello, dear Deer Heroes!
This time, we have released an update to improve the music playback process.
Changes
Reduced the processing load of music playback. This should fix the issue where the game would temporarily freeze when switching tracks.
Fixed an issue where music did not play correctly on certain environments.
Deerchaos！🦌✨
Hello, dear Deer Heroes!
We have a quick update about the development of Deer Hero.
This time, we released a very small-scale update.
Changes
Minor adjustment to Warrior Netro I stage (The stage has been slightly expanded to ease certain situations that were harder to avoid than intended.)
Fixed an issue where the title screen was displayed incorrectly
Deerchaos！🦌✨
Dear Deer players, hello!
Here’s our update plan for Deer Hero.
I’ll add Extra Stages in future updates
as post-clear endgame content, such as:
- Stronger versions of past bosses
- Brand-new flashy bosses
- Special rule dungeons
These are under consideration,
but my goal is to keep you enjoying
even after finishing the main story.
Deerchaos！
