Eh, it's okay...
Well, as others before me have said, it's pretty short, but that's okay. The storyline was also sort of random and pointless, maybe next time take a little bit of time to develop the plot, even if it is supposed to be a small project. The fighting was actually pretty good, but I did notice that you only used three of Kirby's sprites throughout the fight (not including him running). Maybe try to utilize his various movements instead of rotating the same one around to show him jumping. Overall, I did like it, though I don't see how some people think that it was funny.
