*Consctructive Critisizm*
I liked the idea, however I would dispense with the ball-and-hand type characters and try to make them in more likeness of the actual characters as seen in the game. I liked the music, but it was a little "thin" so to speak. It needed more tracks and a heavier drum beat.
I really like the idea, you've got a great start. Try making a sequel with different characters fighting, and try having some objects they interact with other than just their weapons.
