I really don't like AI, but I understand what you're saying. The thing is, the beauty of the game is because it is made by two people, their dedication, love and care, It wasn't just because it's an erotic game that made us (the community that likes the game) like it, it was because of everything I mentioned. I think it's only fair that we, as fans, sit down and try to learn the art style and make some art to try to ease the devs' fatigue a little (if they wanted to).
If the devs allow the community to help a little, I have no problem sitting in front of my laptop screen and drawing until I come up with something that resembles the art style. Even though I don't know English very well and depend on the help of Google Translate and white noise to regulate my hyperactivity, I would be more than happy to help manually with the art, because for me is to truly support.
