My theory
I think the tricky thing about the backrooms is that no matter which turn or entrance they go into the backrooms immediately create a “portal” or alternate maze of some sort that no matter which way you turn lures you deeper and deeper. And even worse once you make a decision, the way you came is never the same. I’m thinking alternate realities combined with never ending side quests. There is no exit. Idk if that makes sense. I am just beginning my deep dive into the archives of Kane Pixels and super fan criteria but, just my thoughts. What are your theories behind the enigmatic mazes that are the backrooms?
