It's just fun to jump through the colorful worlds. Beautifully drawn or animated, innovative level design.
I bought it myself really only because "Kung Foot" what is so funny in great teammate rounds that one is afraid that the neighbors called the police before loud cries.
Another treat is the music levels.
For me, it has a very low frustration factor, since you can save each other from 2 players and there is no "only 3 Life" has limitation.
Even for the woman it is good to master.
The game is worth every penny. Who has not, should beat at the latest at a Sale.
