When I grow up, I wana be just like you :P
I love it. Your work is very inspiring. Some comment on some of the parts:
Animation/Moves: That was very clever. Mixing moves from different styles in each character. Made them feel really different than the actual SF fighting styles. I find myself changing my old SF strategies. Very fun to do.
Controls: As usual, flash controls are never that good. Good job trying to make controls easy to handle (at least easier than SF :P) but still it was a bit buggy.
Coding: I don't know what you used to make this game, but coding a SF clone from scratch is very impressive. Cheers ^^
The only down side I can pin-point is not being original. You had the chance to add your own unique ideas to the SF series, but instead turned it into another SF clone. I mean, with all the time and effort to make all of this, it would be a shame not to add something completely new to game.
Regardless, if I was a monkey, I would give you a 4 thumps up :P
Cheers :)
