Get off your ass and finish it :)
Ok,it does need sound, but even without it, this would pass because of the graphics and the style. Not saying dont add sound, because you should, im just saying it has the potential to fly without it. The storyline was rather silly and needed a bit more along the humor line, but that can be fixed before you finish it. It also seems you didnt get a chance to set the borders correctly on the flash file because we can see everything off stage on the left and right side.
Keep at it and finish it up.
