Thank you for your feedback, and I completely understand your feelings about AI art.
The thing is, this is truly my first game and my first jam, and I was afraid I might not be able to finish it at all or even make it properly functional. Because of that, I did not want to bring other people into a fairly large amount of work while there was still a real chance that I would fail to handle my own part of the project: the code, the story, the music, and so on.
In the future, I will look for artists, because now I understand that making a reasonably functional game is something I can actually manage.
