Not bad.
Graphics: Very stylish and smooth. A lot like the fighting games they were inspired by. And in what, Sonic the Hedgehog's land? Tee-hee.
Style: Well... it was like the anime and fighting games.
Sound: The music and effects were fine, but what were the characters saying? Optional subtitles, please.
Other than that, the biggest thing I've got is either the subtitles/ make the voices clearer. It was fun to watch. My favorite part was when the ninja got hit on the head by a coconut.
