Did you even read the Flash tutorials?
First of all, everything in this damn movie is pixel based, even the dialogue and the projectiles, which are easy as cake to create as vectors. You didn't bother to try to draw the characters yourself, instead relying on blurry jpg's from the internet. You could have at least seperated their limbs to heads to create animation that DIDN'T just look like two pixilated images sliding around a background devoid of color, which is exactly what you did. You probably didn't even use layers, which would explain why the red bar serving as the ground constantly wobbles during the fight scenes. Visuals aren't everything but they really killed this movie, along with the horrible, horrible, "I frequent AOL chat rooms" dialogue. And let's not forget to mention that the idea of Link fighting Mario is completely unoriginal and this lame concept of video game character vs. other video game character has been done to death and so far few people if anyone have managed to make it interesting. It's nothing more than an exchange of words, awful, awful kicking, punching and projectile throwing, with shitty music playing in the background. You obviously have no concept of how to use Flash or how to create a coherent or even half decent piece.
