Sonic Colors is out of this world

While checking out Dr. Eggman's space-station amusement park, Sonic discovers the ol' evildoer is powering his park with Wisps, intelligent little aliens. When Sonic frees one, it grants him a burst of energy for even more speed than usual, and when he picks up Wisps of certain colors he gains a one-shot special ability, like a vertical rocket boost. The game moves fast, and the levels are packed with many obstacles.
