This game has wonderful music, great gameplay with creative level designs and very challenging sometimes. The controls could be better, I dont have a problem moving and jumping (most of the time). But I really dont like the tilting the iPhone around to change its gravity cuz it can get very frustrating (as in it sometimes doesnt respond to my tilting, but its not your fault that the iPhone isnt great at doing this) and the double tap could need some work. It may sound like I hate the game, but I really dont I love it! It just needs some refining to get my 5 stars.
