The Abandoned Schoolhouse

You and your friends have heard that your old high school is being demolished. This place held so many memories for your group, so you all have decided to take one last trip down memory lane through the halls that strengthened your friendships. Unfortunately, no one bothered to prop open the door and you are now trapped. You have only an hour before demolition crews begin to tear down the building with you inside. Unless, of course, you can find a way out of the schoolhouse before deconstruction occurs. Time is ticking away.
