Partially-Eaten Cheese

Partially-Eaten Cheese is an active item that can be found in one of the four chests after defeating the Resourceful Rat.

Effects

 * While active, the player turns into Pac-Man, becoming invincible, granting flight, and instantly killing any enemies they come in contact with. The player can still shoot in this mode.
 * This item can eat enemies that are usually invulnerable: this includes the Gunreaper, Lead Cube and Flesh Cube. The only non-boss enemies unaffected are the Gripmaster, Dead Blow and the Lord of the Jammed.
 * Bosses take 30 damage instead of dying instantly, and the player will bounce off them.
 * Teleporting while the item is active will deactivate the transformation.
