Well...

- Needs A Preloader (Makes the animation slow unless you watch it again)
- There´s no replay button

But it´s actually cool

Color me unimpressed.

Your framerate is atrocious. This is even jerkier than the halfassed old Mortal Kombat games you ripped the sprites from, and it takes real effort to animate choppier than that. The excessive use of static sprites moving in sharp, straight lines also just gives it a really stilted look, and the lack of a replay button is just unprofessional.
