In the game, your task will be to allow or deny entry into the building to subjects who ask to enter it. It seems simple, but be careful, you can't miss a single detail, because you can become food for doppelgangers.

You have recently taken a position as a security guard tasked with guarding a prestigious building. Your mission? To verify the identity of every person who wants to enter the building before allowing them in. But be careful: not everyone is who they say they are!
