This is a question that I thought after reading Level 2, as it says that mice are present there. This implies that other animals could be found around the Backrooms. What do you think about it?
Most likely; unless only humans can noclip, which I don't really believe, other species would probably be present in the Backrooms. Noclipping seems more like a reality glitch than something only humans can do.
I feel like it would definitely be possible, but It would be insanely unlikely one would get past level 0 even, unless one would be lucky enough as to no-clip into level 1 at first.
True because earth is decillions of light years away from the edge of our REAL universe (Not the observable one, don't say I'm wrong because of that, I still might be wrong though) and our universe is whatever this is 1.86e+12
