In your bedroom, use the window and talk to the voodoo chile behind it. You’ll learn that you’re dead.
Leave the window again and walk into the hallway on the left. You can visit the bathroom north but there’s not much to do there. From the hallway walk down the stairs on the lower left to the living room and walk left to leave the house. At the town square use the third door from the left to enter a toilet.
Use the toilet to finish the game.
