Nothing short of a bad movie
Let's leave a good critisizing review, shall we?
Graphics: Mostly they (the sprites) were overtweened and blurry, so I didn't really notice any true pixelated glory. You may want to try your hand at drawn movies for a few months before coming back to collaborations, so as to make sure you have a good sense of quality work.
Style: Style? I'm sorry to say this, but sprites are overused. Sure, there are a few good spriters out there, but unfortunately you haven't yet reached their standards.
Sound: You actually did OK finding sounds here, so it seems I won't be able to give much critisism on the subject. You may, however, want to add a little more variation to the sounds rather than "OWOWOW" and other such generic sprite sounds.
Violence: Well, I must say it was violent, but needlessly so. You may want to add more variation to the fighting and keep us from falling asleep.
Interactivity: Well, you have a menu, preloader, and scene select, but other than that you can't expect much out a movie. Not much critisism to give here...
Humor: Not funny, so you may want to add a little more humor if you plan on getting a higher score in the portal; NGers love humor.
Now if you're displeased with my review, don't go bitching about me not worshipping every little second of this movie. You've got potential, so if you don't give up on your animation, you'll soon be up on the frontpage (well, maybe not TOO soon). Good luck with that, anyway.
