Hall of Infinite Doors

as you enter into the next room you come across what seems like a vent system in the ceiling. seeing a rope, you grab it and throw it up into the hole. Getting it to become secure, you climb up the rope and into the vents only to find out it wasnt a vent, but a series of tunnels. As you walk along, you see another door leading into a room and open it. The room you see seems to remind you of your childhood. Something looks oddly familiar when it strikes you. This room is an exact duplicate of your toy doll house you had when you were 8, only its so large that you could live in it. As you begin walking around you hear a noise and look over to see a silver looking object which you indicate to be a bomb. You look around, with 4 doors you could run out back into the series of tunnels.
