Un..realistic?
One reason why the goal in SSMB is to knock your oppenent off of a stage, is because the fact that in a fight like Link VS Samus, Samus would undoubtedly win. Once Link, who's unarmored by anything but a Tunic and various Hearth Containers, is shot by a large beam of electricity, he would most certainly die.
Anyway, I liked it because... of.. the music. I gave you a 1 though. If you touch it up some more, it could be even better. I'm not disappointed because it's a sprite animation, but because the graphics just... need a lot more work. Especially with the sprites you chose. If you're going to do a sprite animation, at least do it right.
