AI disclosure This game uses generative AI in the following way: Some background music and ambient audio tracks were generated locally using ACE-Step-1.5, an open-source music generation model run on the developer's own hardware. No third-party copyrighted audio was used as input or reference material. All generated tracks were reviewed, edited, and mastered by the developer before inclusion in the game. The developer holds all rights to use and distribute the resulting audio under the model's permissive license. No generative AI is used at runtime - all in-game text, dialogue, narrative, voice lines, and game behavior is hand-authored and deterministic. The shipped game does not connect to any external AI service.
