Store page and marketing capsule artwork was drafted with generative AI, then quantized to a fixed 9-colour pixel palette and hand-adjusted before use. Interface translations outside Simplified Chinese and English were produced by machine translation and have not been reviewed by native speakers. All in-game visuals, the user interface, the wordmark and the achievement icons are drawn programmatically in code and contain no AI-generated content. The game does not invoke generative AI at runtime; nothing is generated while you play.
