Although I dislike the designs, it looks good and is well animated. However, there's so much shot going on with their cartoony fight animations that you loose track almost immediately.
And these animations tend to go on forever. Also, the ennemies are lying way too long on the floor before getting up again. All this kills the flow of the game, it's a sluggish mess the way it is now. If they shorten some animations, accelerate them, their movements and the ennemies, then it could become a pretty good game - but not like this.
