Couple of things...
First, i think the mouse icon should revert when you get to the movie part, because it's just distracting! Second, i think the whole bit needs to be more linear - maybe have a collective plot or something? And, as always, i think people need to learn how to do pixel art, but that's just my opinion.
The rest of it was really good - i liked the mario thing, but the Goomba seemed to be missing a few pixels when it walked, and that part could have REALLY used extra pixel art for the gun and the crater.... that would look really impressive. The sound was kind of lacking, but maybe that's just because i'm really tired and not in the mood for it?
Any way you look at it, it was a pretty decent submission and i'm betting it'll go through, and i'd like to see future collabs from you guys!
