Too formulaic

It just seems to be one hits the other guy, then he retaliates, then the first guy attacks again, etc... Put in a bit more variety in who attacks when.

Other than that, great idea pulled off fairly well. :D

An epic

This goes right up there with "The Snowman" in terms of artwork and greatness.

It is however, too long, and I can forgive that up to a point, but still too long.

5/5
9/10

Where did it go!?

A good try, but it's too easy to completely lose the pointer off the edge of the screen. Apparently once that happens it becomes impossible to get back.

This is great

Great work on a classic of a game. Great sound to it.

This is great

This is a great piece of work. Don't stop now... ;)

No consistency

There are some good riffs present, but it all seems really disjointed. Maybe that's what you were going for, I don't know, but it doesn't sound quite finished. There's too much stuff NOT happening if you know what I mean.
