What I liked: The art style is super cute and the ripple effect in the main menu is a good touch. Clever puzzles.
What could improve: Consistency between puzzles. I know its supposed to trick you into not knowing which door to trust on each level but some better indicator on why the solution of the previous level do not work for the next one would've been great.
Additional thoughts: All in all it's a good experience. I'd remove the platforming as it doesn't add much to the experience or atleast make it so you spawn back on top of the screen instead of dying since dying to the doors is the main hook of the game.
