I have mixed feelings about the use of generative AI in videogames, however that did not factor into how I rated it. I feel it would be nice to have a bit more information on how you used it. I do think that it has the potential to be used ethically (although that isn't happening in the industry at the moment) - so long as it is not replacing work that would have been done by human artists - so learning about how you used it and your aims for the project could be an interesting addition to that discussion.
That aside, the graphics look nice and the game has a great visual tone, and it certainly looks like a stylised and modernised version of 1990s visual novels/point and click games.
