Make your way to the door.
From Create Your Own Story
You walk to the single door on the other side of the space. It has a tiny square pane of glass in the middle of it, which you move to look through but can see nothing except a very blurred reflection of your own face. The door is clearly sturdy, made of solid metal and displaying no handle or mechanism with which to open it. Stepping back for a moment, you consider breaking the small glass pane; it certainly isn’t big enough to climb through, but it may grant a glimpse into what’s on the other side.
