Hello everyone!

After roughly a year and a half of solo development, Sin Spire has officially launched on Steam!

I started working on this game in the summer of 2024, and it would not have made it to release without the support, feedback, patience, and encouragement of a lot of people along the way. Thank you to everyone who followed development, wishlisted the game, tested builds, reported bugs, or simply kept an eye on it – it means a lot to me.

Sin Spire is a first-person erotic dungeon crawler built around a set of five procedural dungeons. It’s intentionally harsh at times, and you must learn, adapt, and push forward. You will start out weak, but by the end you may become a powerhouse.

The game currently features full English support, along with subtitles and UI text in Russian and Chinese. It’s expected to run on most systems, though there are some performance issues on the Steam Deck (around 90% of the game is still playable there). This release also includes full Steam integration for Achievements and Cloud Saves. Community items are tied to a game’s popularity, so I can’t currently confirm whether those will be added in the future.

Known Issues at Launch

I want to be upfront about a few known issues that may affect some players. It might seem odd to include a section like this in a final release post, but I felt it was better to set expectations clearly, as these won’t be fixed immediately.

• Dungeon generation issue (late-game dungeons): In the final two dungeons, dead ends may occasionally appear. If this happens, reloading the save or backtracking to regenerate the dungeon should fix it.

• FreeMode purification animations: Viewing purification animations in FreeMode can result in enemies becoming frozen on the final animation frame.

• Talker NPC scene interruptions: Some animated scenes with Talker NPCs may randomly interrupt. The cause is currently unknown.

• NPC disappearance near endgame: One NPC can disappear after reloading a save near the end of the game. This does not block progression.

• General issues: In my final round of testing, I found a few minor issues that don’t break the game or affect gameplay. These result in some occasional visual oddities, but nothing harmful, and I don’t consider them significant enough to risk a hotfix at this time.

Looking Ahead

The focus going forward will be on bug fixes and minor content additions. No major expansions are planned immediately.

I’ll also be shifting focus toward future projects and, probably most importantly, taking a short break in the immediate future.

Thank you again for the support, and I hope you enjoy Sin Spire.
