Amazing
Honestly I probably would have rated it a 7 if it weren't for the skip feature as there were some levels I never understood even playing the last time. I did not like how you had to play as a different charecter in order to unlock medals but hey at least it was a bit different. I have never played a game like this before, however reading some reviews other people have. You should definitely consider a sequel with a level editor so that there may be some user generated levels, I would definitely contribute to it. Rating Time!
