I think it's a bit unfortunate that you used AI for all the non-core elements of the game like the artwork. I do think that a game with judicious use of gen-AI allowing you to go "off the rails" has potential, but it's going to take a lot of hard work to make it OK and not chock full of all the AI clichés. It can be a good game, but you need to avoid not only to make it not look like slop, but avoid it BEING slop, and it's like you don't quite appreciate the problem when using AI for things you don't even need to use AI for.
