Amazing artstyle! Especially impressive for a 2 person team, since there's a lot of individual assets that all have charm and cohesion. Everything is nicely animated and polished. Hats off!
The undo last move feature is greatly appreciated, the visual playback on it is clear.
If I'd have to give one point of feedback, the pacing of the level design was somewhat inconsistent. Some levels basically played themselves, whereas others were quite complex and tough, and this difficulty seemed somewhat random (not gradually increasing in complexity).
