What makes this game so good is the combination of the three parts: playing, creating and sharing. The platform gaming is unusual and at times brilliant, but it isn't perfect. The controls are a little floaty, so you will fall off things when you don't expect to and die. When you die, you are "respawned" at the closest checkpoints. For each checkpoint, you have a limited number of lives, so occasionally, when you have hit a particularly challenging section, you may use up all of your lives and have to replay the whole level again. This is not a major complaint, particularly because there is so much to see in this funky colorful world. The bottom line is that the story mode is good enough to justify buying the game, even if it's all you play.
