Beyond Liminal (early access)

"If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately "a lot of" miles of randomly segmented empty rooms to be trapped in." Music that can be heard in this game are by The Caretaker and K Pixels.
