cool music, very simple concept, well executed. The transitions, and animations in general were really nice. Having an actual settings menu - a neat touch :) you got the rhythm in there for sure. It's not so easy that it's boring, nor so hard it's frustrating (though obviously you won't complete a level on your 1st or 3rd try). You got the difficulty just right :D The design of the levels and characters, especially the protagonist is really cool too! (I love the little bunny ears ^^ ) Criticism-wise, I'm not too sure about the pink... thing in the underground, it looks like a placeholder, so I assume it's that..? You had a tiiiiiny bit of a story/ context here and there, maybe a line or two of dialogue or just exposition could have made the story a bit more engaging (although it still works - you're simply running away from the bad guys)
