Aaaand played a demo of this I got from the Nintendo Channel.
All I can say is: the Teleport Jutsu on the "L" button breaks the game, greatly. I mean, I may just buy this, so I can kick various weeboos who love this game's butt, with just light punches and teleport Jutsu.
I mean--it is nice that there are combos and everything... but I generally do not use combos in these games... and well... for some reason I can never pull them off. (I still have issues doing Ryu's fireball in street fighter--I dunno, I think I adjusted very nicely)
