Good, but slightly flawed in some respects.
The choice of characters were great, and their stories were more then interesting (Piconjo's was my favorite, priceless smile).
However, some things really bugged me about it.
-Infinite air combos- The computer loves to abuse this with Samurai Asshole, but it's pretty much possible with almost all the characters. Since you go upwards with each air attack, you saty aligned, and thre's little cooldown on each attack, so if you hit them at the right angle, boom, infinte. There's juggling, and there's infintes. Two different things.
-One at a time now!- I don't mean this as one on one fights only, but if you're going to put multiple adversaries in, at least make it possible to hit more then one of them at the same time. If two opponents are right next to each other, you can't beat them, because you'll only hit one, and the other will beat the shit out of you.
Other then those two main things, the game was awesome.
