Very nice concept, if fits the theme well. The music was "goofy" and that fits the game too! The artstyle is charming, and the dying animations are EYE CANDY. The game is a little bit too trial-and-error (as @picross said) but I don't think that's a problem, because when we die we can quickly restart the level. What I don't really enjoy in this game is sometimes the level design, when the correct path to win the level involves passing by the enemy so close that is hard to get right.
Good job, developers!
