Exploring the Outside Inn

Some doors open out, and some open in.  Exterior doors let you out when you're inside, and in when you're outside.  Interior doors lead from room to room, or from room to hallway or hallway to room.

There are front doors, back doors, side doors, garage doors, secret doors, and hidden doors, to name a few, and all serve to let you pass from one location to another - locations typically separated by walls.

But some doors are different.  With the right key, some doors don't just lead to the other side of the wall, but to other places altogether... with the right key, some doors let you out from outside or in from inside, and some doors let you go back before, rather than just back through.

With the right key, you might even find yourself at the Outside Inn.
