Level !

Description
Level ! consists of a long hallway, approximately 10 km in length, with architecture resembling a hospital. Flashing red lights are present at even intervals along the hallway, along with an audible emergency alarm noise. At random intervals, doors are present along the hallway, but all have been locked thus far.

Properties
Once you enter this level, you'll immediately notice that behind you there is a horde of entities (Hounds, Skin-Stealers, Facelings etc.) running directly at you. Your objective is to escape the level as fast as you can before it's too late. The only way you can escape is by running all the way to the end of the 10 km long hallway. You'll have to run non-stop, with various obstacles, like hospital beds, chairs, and even through clumps that are blocking your way. Along the hallway, there are energy bars, which can be eaten to keep you running. If you run past the 10 km mark, you'll find an exit door at the end of the hallway. Entering it will lead you to a random level that is safe, with the Backrooms never sending you back here again. But if the horde of entities catches you, you'll be killed, likely in a painfull and brutal way.

Log: Discovery Of Level !
Operative Noah was in Level 2 on his way back to a colony called "The Survivors", trying to deliver valuable information about The Followers Of Jerry, when he anomalously appeared in Level !.  

Colonies and Outposts
Due to the nature of Level !, creating a colony or outpost is infeasible.
