Catboy's animations are fantastic. I love the way his arms flail when running around, or how he bonks his head when jumping into the ceiling.

Overall, it's a short but sweet game. The first and last third of the game have story reasons for exploring each level, but the middle chunk of the game will just send you to a random level for no explained reason. Fortunately, each biome is well designed and fun to explore, with some fantastic music to jam to.
