I am having trouble figuring out how to get past the "three alters" and get to the "goal ring" in the game...can you give me a hint on how do you get past that part in the Mystic Mansion - Sonic Heroes game?

You have to get through the obstacles of each alter's section. Each is generally suited to either your Speed, Power or Fly character. After completing one, you're given a warp back to the main area. Once you finish all three, a new warp opens up in the central hub.
