4/5 and not 5/5 because even though new powers in the forms of the wisps. (i.e the frenzy, drill and cyan wisp to name a few) it's controls layout is horrible.(on the solo wii controller without a wii nunchuk) this game has some nice touches, first you can unlock super sonic in it, and you can come back to earlier levels with wisps that you previously didn't have like the drill or hover wisp. but having the patience required to collect all red medals (a collectable and requirement for super sonic) is rare unless you're really dedicated so... have at it I guess? But back to the wisps. The wisps themselves are a good addition to the game, to also help it give a a reason to back track and really explore.(except for the rocket wisp well... it's meh at best)
