Could be better.
It's a sprite movie where the quality of the sprites seems to vary (blurred, non-blurred, or 8-bit?) and clash, but never really excel. One factor of the SSB is that the camera constantly zooms and scrolls to make the fighters the focus of the screen, so it looks more dynamic when the fighters move. None of that shows up here.
The movement of the characters is slow and badly implemented. The sprites should move around more naturally instead of using diagonal jumps and floating over the arenas.
On the whole, it's a nice idea, but one that's very badly executed.
