It looks awesome and its a very interesting design. Although it's very difficult and I felt it is sometimes impossible to react when there's a ton of face with multitudes of colors approaching, ie. a yellow and then a blue right on top. If something like that can be worked around then I'd probably even fave this.
I loved every aspect of this game... my only problem was that the sound effects were a bit cheesy and didn't really suit the genre and the concept of this game.
