Tips
- A hard counter to the debuff items is having a completely full inventory
- The Ankh Shield is a must have, as knockback could knock you into him and that means you don't have to worry about the screaming head.
- Counter the flipping with Gravitation Potions or the Gravity Globe although that means that in addition to flipped controls you have to deal with left flipping the screen, so pick your position
