Bullet visibility during that boss fight seems really good, thanks to the blinding lights dictating the flow of most of the shots and outlines generally being very crisp, neat.
There are last words in this game? First I've heard of it Also I never really understood how Youmu is OP in this game, both A and B, as the slash barely does any damage, the focused movement is ridiculously fast, the ramming spirit seems a bit wonky for its damage, and her main damage is unfocused, which you can''t do all the time
Her A(or B I guess?) Could literally melt boss HP, just repeatedly tapping focus do the trick. (Unless if they changed or nerfed that after the Extra Update, haven't played it since the earlier updates).
