For me its like the wiki is dead.
Good-bye.
I have measured the chances are approximately.. 0.00000000000001% on getting out of there depending of what level you are now, your chances are survival are very low so your pretty much screwed.
I believe there's an infinite amount of levels on the backrooms, same for the abnormal levels or "The Hub", to find an exit there's an incredibly surprising small amount of chance that you will get out by no-clipping out of that dimension.
