Pros: Great Co-op, puzzles, and gameplay.
Cons: Single player option is not meant to be.
It looks childish. It looks easy, and simple. It basicly is, and that isn't so bad.
Real Cooperative Game Play
This is a game where you almost must have two players, or you are doomed to losing the moon for ever. Though, if you are trained in doing to different things with both hands at virtually the same time. Also, you must build trust and timing this game could start world peace or something, because if you don't have a dependable partner, your doomed.
Game play of the future...sort of.
Very simple game play. One button for jump, one for action, and the analog to move around. Easy to learn. Except that there are challenging puzzles, funny movements, and odd idea tossed in to make it much more interesting.Example : You wanna cross a canyon. Your friend will have to do something(i.e. push a button, spin a knob shove a log, ect...) to help you overcome this problem. Sound simple? It should. It isn't though, as the things can be hidden, and enemies might be near by. There are 6 worlds each w/ 5 stages. By getting puzzle pieces in the first four stages of each world you unlock a character in the versus mode.
Straight from cartoon world.
This is a cartoon, and remember that when looking for solutions. If you don't have a sense of humor, you won't get anywhere.
If you have a friend to play this with(and you both like humor) then you should get this game A.S.A.P. Otherwise, forget it. I mean that.
