Since it was made by only one person, it is amazing!
Game play: It is very cool, because you can do lots of things you can´t in other games, like eating mushrooms and flying to the sky, defeat ninjas in your own way. Even if it is short, it is fun playing again or playing the mini-games. It is all about Chi power.
Graphics: I don´t care much about graphics (as long as i can clearly see other things), but is very nice seeing those explosions and the chi flowing from your character. The cut scenes are stupidly funny and very enjoyable
Sound: The sound has a great quality, the musics are very nice and it is cool to use the mixer.
Value: I really think that it is worth it, because it is fun to play many times or play with other people.
Remember, it is all about Chi power.
