AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

We used generative AI tools during development to assist with some pre-rendered content: drafting store page text, producing UI layout mockups and some UI sprite assets, and generating base meshes for a portion of 3D props (which were then reviewed and edited by the team). All gameplay, code logic, and final art direction were created and approved by the developers. The game does not generate any content with AI at runtime.
