I like the game's gimmick of flipping between two different states whenever you jump, kind of like some of the levels in Super Mario 3D Land. The controls are generally fine, but the wall jump sometimes felt weird — if you press the other direction from the wall a bit too early, you'll fall off and won't jump. The game being short is understandable due to the time constraints, but I do wish there were a few more level segments to introduce elements like the walking mushrooms in a safe environment.
