ending ideas:
Torch the Tower - burn the host with gas, then lose the game. Ends the host's cycle at your sacrifice
Escape - BOOM! Axe to the neck. BOOM! Axe to the jugular, BOOM! Axe to the door while he's distracted (or crowbar)
these were just some dumb ideas I had, you don't need to do anything with them I just wanted to put them out here
