Let's say you manage to make it to The Frontrooms, only to noclip again. What most people go with is that you're... just in Level 0 again.
But my idea says otherwise (in an UNcool way!1 :face_vomiting:). I call this The Return System.
So first, you noclip into a dark room. You see 2 entryways. One lets you in Level 0, that's obvious.
But what the fuck does the other one do?
It sends you to a new set of Levels, all of which exceed the dangers of the Backrooms. This is stupid, I know.
Then let's say you make it out again and noclip also again. You get sent back to the same dark room, but with a new entryway to even harder levels. It's basically a rebirth system.
Now, we can't just keep adding new entryways forever. Just kidding, the room will just be bigger to be compatible for more! Easy.
