Do you want to prank your friends by putting them into liminal purgatory? This is the mod for you!
This mod adds various Backrooms-themed blocks for you to build your own winding disconjoined maze of fluorescent lights and ugly carpet. Or... you could use them for your house. We don't judge here.

I found something.
Okay. What did you find?
Found a place.
It's massive in there.
And it just goes on and on and on.
All these rooms.
This place builds them.
Actually, more like it... remembers them.
And the more times it remembers something, the less it does.
