Congrats on making a whole (butt) game in 48 hours! (Sorry, I had to...)
The puzzles are interesting, but a lot of similar puzzles have been seen across the jam... It would've been interesting to see how the player character being a rat affects the kinds of puzzles they would encounter or something else to jazz it up a bit. The puzzles you do have are clever, though!
Also, something about the music felt a little... off? I can't explain it, but it just made me feel weird.
