This game is fairly short and can be beaten in a matter of ten minutes on the easy route, but it does provide other secrets and ways to go about the game.  You can go through three main paths, but you can quirk the paths if you decide to or if you screw up on one part of the level.  You definitely will find yourself going back trying to unlock the different multiplayer modes and trying to up your high score.  The rumble pack is worked very nicely into to the title.  The voices are also a nice added feature.  Buy this game guys.
