I really like the polish and all of the little details (like his eyes following the movement of the traps), however I think that the level design tends to be unfair sometimes. I've also encountered stages where I was dependent on blocks falling down to accelerate axes. Sometimes the blocks just wouldn't want to fall down, sometimes the axes would actually get slower. I'd enjoy it more if it wasn't that frustrating.
Disclaimer: I haven't finished the game because it frustrated me that much.
