Aside from the obvious, which you've already covered and I'm very appreciative of that as a fellow artist who also used to play around with those old AI generators before the truth became well known, this was an absolute amazing game. After what the first two paintings had to offer, I wasn't expecting it to jump into that kind of horror though, which nearly gave me a heart attack, despite Charons' warnings. 

It'd be amazing to adapt this into a bigger game with more paintings, characters, stories, in-depth lore and world building, and good body horror art.
