Graphic adjustment regarding fighting against dark characters on stages with dark background

4cyke

I found it's very difficult to see certain characters' movement in battle with dark background，
for example ： Void in the stage with a giant statue head spewing lava . half the time i can't see whether he's guarding or not. blade and a few other dark characters have similar problem ，but not nearly as bad as void.

please consider improving their visibility . and please ,don't make those flashy ones , or ask me to turn up my screen brightness , this game is eye-strainning as it is.

thanks.
