Fast Attacking!
Too many flash games with fighting have really slow response time for some reason. They need to take a lesson from this, cause the response time is great. I think it deserves a much better rating cause it seems so much has been put into it. But even with the fast response time, this isn't the kind of game that many people would really enjoy playing. Not completely sure what a fighting game would need, but with flash games it seems they just need something new. The flashback is cool, but not enough.
Also, as for style, i dont know what other people think, but i'd like a drawn background more than 3d. And i dont particularly like any of the characters.
