added dupe as an entity

since you dont see the door tag things dupe's room will only appear right in front of you

when you get into a room which has 3 doors go into the door behind you

also dont rush unless you are in a chase since dupe doesnt appear in chases, dupe will try to trick you to run into his room

by the way dupe doesnt deal a specific amount of damage, he just instantly kills you so be more careful
