I used to play this game a lot when I was younger. I came back recently to find that they've changed the way that the game is played for the worse. It used to be that after a certain point, you are able to go to any of the different worlds at any time. I come back to find that they've changed the awesome time-hopping aspect of the game and removed it. Now it's no different than any other linear level-by-level game. Boo. If they for some reason change their mind back, it gets 4 stars.
