Based on an AI image. Sorry, but that's not "No generative AI was used"; that's AI was used for Art Direction.
For your peace of mind: I changed it to:
What kind of AI-generated content is used? -> Graphics
However, this isn't correct, since only parts of the cover image were created using AI. If this site is requesting this information, it should be more specific.
Sprites and the rest of the graphics were created using traditional methods with appropriate editors.
