Damn hard, but well made!
I just put it on infinite mode and i gotta say, this is VERY hard for me (dunno about other people.) It's also very well made, with good graphics, nice sound, sweet combos, and suprising smooth gameplay. Didn't see any bugs either. My recomendations for an even better game would be some sweet power ups, upgradeable weapons, more combos, more characters, level select, create a character, you know the deal. Well anyway I think you the potential to make a nearly flawless fighting game. Well done!
