I cant tell if the game is actually hard even in normal difficulty or i just suck, cuz that last boss is wiping the floor with me lol
Practice timing
Hold down arrow or whatever if you use stick to guard
If boss attacking , either goes to left or right with dash
If boss puke , obviously guard
IDK , somewhat lv 75 is when I beat the boss. If dat help
Or perhaps less than dat for some people
Focus on Atk Def Critical
