BLINDFOLDED? Are you insane? First I thought it is a bug, that the screen dims but it is actually a mechanic? That is just crazy I spent a lot of time practicing, and I couldn't yet beat him. But I am not going to give up. Also for the boss, it would help to have a healthbar or a incoming warning, that he is planning the big attack. There is nothing as frustrating as to not have enough ammo for the big attack.
