Wow, this one's amazing! Incredibly creative and ambitious concept to take on for a game jam, and super charming art and execution! This is a special one!!
I have two critiques. One is that it would really help to have some semblance of an idea of where to go. I'm guessing one of the rooms is randomly the "exit room," and I'm sure you're aiming to capture the feel of being truly lost in a shifting labyrinth. But I think having an idea of like "I probably want to go down and left" goes a long way for establishing player goals and feeling that tension between what I'm doing and what the maze is doing (as it stands, I didn't really mind if it shuffled things around because I couldn't tell if I was moving closer or further from my goal).
My second critique is the skeletons, I do not love that they can jump further than the screen can see. Unavoidable combat damage is...something I would avoid as a rule, personally.
However, I only say these critiques because this game has insane potential, and I honestly really like it! You all did an awesome job, super well done!!
