I appreciate the AI disclosure - uhh, I actually really liked this. It gave me strong survivor horror/backrooms vibes. Like, I couldn't quite finish the last level, and every door I went through I wasn't sure if I had been there before. and there were some definitely creepy moments. Definitely potential with jump scares / music, and puzzle elements that stress the player out.
I wouldn't change the asset style at all, rather, I would lean into it. In one room there was a clock that was placed far off the wall, and you could see the shadow. I liked the repeating portraits (whatever that was).
