About generative AI
Character 3D models and textures were created with Tripo AI from original images prepared by the developer. ChatGPT / DALL·E were also used for UI icons, background art (sky and grass), and some textures. All results were reviewed and adjusted by the developer before shipping. The game does not generate AI content at runtime.
