You are walking along the Backrooms, before stumbling across a door with an exclamation mark on it. The legends of Level ! stated that a door with an exclamation on it was the way to enter, and so you did, but...

When you entered, you saw no red lights, no extreme ambience, no monsters chasing after you. You instead saw a dusty, old hallway, with some of the "Exit" signs that were attached to the roof on the ground, fallen due to age. The walls had moss on them. The place looks abandoned.
