Very wall made
Excellent game, one of, if not the best on Newgrounds.
Only problem I can see is in some of the 2 vs 1 or 3 vs 1 fights. Occasionally, one of the computer characters will stand still doing nothing. Also, if you start a combo on one character, none of the attacks hurt the second character until the combo is finished, which can be quite annoying. I also dislike how you can't hit both opponents at once.
Still, that's only a minor flaw and doesn't spoil the overall playability of the game.
