They will make you "help" them beat this. Not bad for most games, however after a little while you will discover the only way to beat this game is to literally destroy it. The audio combined with the controls is enough to make any sane adult violent. Then you will have to explain to your children why it's perfectly O.K. to break things that are truly evil, and have to pay gamefly for the game.
I am 40, so I may not be the target audience for this game :) I was expecting something like Zelda, but instead it was just too childish for me. I found this game really annoying right away. I could not make it past the initial game play.
