Overall; crappy
It looks ok-ish. The music is damn good.
But oh god, the glitchy fighting... the pace is right, which a lot of games don't seem to get, but the hit test for the people and the attacks are so far off...
And it's so unbalanced... Naruto's special move does the same amount of damage as Sasukes, but Narutos is a guaranteed hit, becuase it stops everything else. Sasukes has such a large amount of time to charge that you can knock them into the air, then start charging it and they have enough time to land and hit you before you have half finished...
I have also found a glitch; when you are playing as Sasuke and you start charging your Chidori, and Hatake Kakashi uses his ninja dog summon a few times in a row and hits you while you are charging, you no longer can move...
Also, platforms and a larger map would be nice...
Despite this games overall crappiness it is quite fun to play...
