It was a good game, UNTIL
The only major flaw, I can see, is the controls. Every couple seconds I have to reclick the game or scroll back up to the game or the window will freeze because my browser doesn't like what the mouse is doing. Really that would be the only thing I'd fix. Regular fighting game controls aren't SO bad, are they?
Otherwise, its a really good game, I just can't get into it with mouse flying all over the screen.
