yep
This is one awesome game, I used to play SSB all the time. The added characters really add a touch too, Knuckles and Lloyd can really do some ownin.
The two main problems I had though were where you'd get hit while runnin fast towards ur opponent and it sends ya flying, and then there's those Angel Island platforms which were pretty glitchy and the character often fell through them makin it stressful to complete the level.
