the backrooms are an endless series of places, consisting of yellow hallways, office places, and even pools, but each section is split up into levels you and your companions have to navigate through. there is a chance to get out, but it's nearly impossible. there are also creatures named "entities" that roam around the backrooms, looking for people to kill. they will chase you and try to kill you on sight, so make sure to avoid them if you can. and if they do see you; RUN.
