the super saiyan hedgehog is VERY VERY VERY distracting. is the aura effect REALLY necessary?
mario and samus's standing animations are very fast too, might wanna add more frames to slow em down or lower the frame rate or somethin.
that and...this brawl thing has been done SOOOOO many TIMES its like the only thing people can think about when it comes to sprite fights now adays. so 0 for originality.
