Deaths are one of the mechanics for the 123 Slaughter Me Street series.
The Follower will attack the player if they haven't check on him nor keep their flashlight on while walking down the stairs.
If the player wasn't careful enough to check on the Greeter and lets her contact the player while peeking out from the doorway, she'll immediately attack them.
If the player hasn't check on the Waiter carefully nor hear his growls, he'll quickly attack the player.
The Seeker will attack you if he sees you
The Greeter (Revenge) will attack you if she sees you
The Screamer will not really care if he sees you but he might chase you
The Nightmare will come out of the shed and kill you if you stand by the shed
The player will be killed upon getting contacted by one of the puppets. Unlike other installments, this game does not feature jumpscares.
