Sin Spire

Sin Spire is a first-person erotic horror game with a retro 3D style set in a series of procedural dungeons. You play as a nameless wanderer who must defend himself against a large cast of female monsters. Engage in horrific yet erotic encounters and do your best to escape the Spire.

[p][b]Hello everyone![/b][/p][p]After roughly a year and a half of solo development, [b]Sin Spire[/b] has officially launched on Steam![/p][p]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.[/p][p]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.[/p][p]The game currently features full English support, along with subtitles and UI text in [b]Russian[/b] and [b]Chinese[/b]. 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 [b]Achievements[/b] and [b]Cloud Saves[/b]. Community items are tied to a game’s popularity, so I can’t currently confirm whether those will be added in the future.[/p][p][/p][h3][b]Known Issues at Launch[/b][/h3][p]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.[/p][list][*][p][b]Dungeon generation issue (late-game dungeons):[/b] 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.[/p][/*][*][p][b]FreeMode purification animations:[/b] Viewing purification animations in FreeMode can result in enemies becoming frozen on the final animation frame.[/p][/*][*][p][b]Talker NPC scene interruptions:[/b] Some animated scenes with Talker NPCs may randomly interrupt. The cause is currently unknown.[/p][/*][*][p][b]NPC disappearance near endgame:[/b] One NPC can disappear after reloading a save near the end of the game. This does not block progression.[/p][/*][*][p][b]General issues:[/b] 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.[/p][/*][/list][p][/p][h3][b]Looking Ahead[/b][/h3][p]The focus going forward will be on bug fixes and minor content additions. No major expansions are planned immediately.[/p][p]I’ll also be shifting focus toward future projects and, probably most importantly, taking a short break in the immediate future.[/p][p]Thank you again for the support, and I hope you enjoy [b]Sin Spire[/b].[/p]
