As the door closes behind you, you notice that there is no handle on this side of the door. You start to grab at the door, but it slips from your fingers and closes. You're stuck on this side, and you turn to see what your options are. To your left, there's a spiraling staircase leading down. To your right, there's another door. If you go through the door, you may find yourself locked out again. On the other hand, that staircase could take you anywhere. You can't stand still any longer. It's time to decide.
