There's some really cool ideas in here! I really liked both the hiding mechanic and the puzzles where you needed the enemies to push the box for you. The art style is really good too. I like how the character's style didn't quite match the rest of the world, which makes sense thematically.
Only real complaint I had was how floaty the jump felt. I would have trouble going up small steps if I wasn't holding the jump button down every time.
Overall really good game! It's pretty lengthy too, though that might be because I failed a lot lol. Good job!
