Cuphead but I can't change weapons, charms, or super arts (READ DESC) (PART 3) (DLC)

I will be playing in simple mode, and I will skip the devil, king dice, and chef saltbaker bosses. I will only play mandatory bosses so I will not play any mausoleums, run and guns, secret final boss, and the king's leap bosses. However, if I die 3 times in one isle I must restart the challenge. I also must get at least a B- grade on each boss.
