The Backrooms.

Alone. Its dark. Your on the 99th floor. You-ve ran out of supplies. Your only hope now is that this level gives you the elements you need. One more floor. Freedom. Its been months, you have lost everyone you met on the way. You can get it all back, just go through the exit. Find the exit. Locate it. Hurry. Run. Almost there. But then you realise, your in a simulation.
