i dont know if this is a bug or maybe im doing something wrong, but despite having 4+ crushed cans/bottles, you can only use one of each against the zombie/creepy person in the hallway when you first start the game. I can't proceed if I've already used the cigarette to save either, forcing me to play a new game ):
Edit: for clarification, this is after collecting all cans/bottles in the starting room, which includes several crushed cans, leaving the room and initiating the encounter, without using any of the items to heal yourself.
