Shouldn't Nintendo be suing your ass?
Seriously, how did you do this without going through extreme liscencing? It's not even parody. Just blatent theft of the publishers property.
As of the game itself, it's pretty bland. Two attacks per character, unoriginal theme and settings. Why don't I just go play smash brothers? Or a better flash by armor games like Unreal. Not worth it.
And in regards to the previous commenter, I agree with you, but there's no better way to prove you're right than to put up or shut up. Less words, more better flash games.
