This game gets props for its incredibly unique style of gameplay, and has a lot of charm for those who are looking for something different. When you first play the game, you'll have a great time just watching the cute characters and their goofy little tunes. They still play in my head from time to time ("kick! punch! it's all in the mind, if you wanna test me, I'm sure you'll fiiind...") and brings a smile to my face.
That being said, besides the charm and originality, it's a short game that's hard to keep playing seriously once you get past the originality. Definitely a game for collectors, but not one that serious gamers will get into for any reasonable amount of time. Different game modes would have been nice, such as split screen vs battle or something. It's a game that was meant to be shared with others, but ends up being a charming but lonely single player experience.
