Not bad
I love the concept and the action. However, by uploading the full song you made the loading way longer than the VERY short movie. The fighting was okay, but it seemed cheap how they teleported all over the place with the white line thing. Maybe you should do something more like those street-fighter animations (although you should keep the original Mario idea and the enviroment interactions). Oh, and make some kind of differance between the Marios, like Evil marios wearing black or something. All-in-all, good job.
