Backrooms - Level Pizza

"If you're not careful and you no-clip 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 six hundred million square miles of randomly segmented empty rooms to be trapped in.

God save you if you hear something wandering around nearby, because it sure as hell has heard you." - Unknown

You have, in fact, no-clipped into a level of the backrooms inhabited by both good and bad.  Unfortunately, the bad is a flying sentient pizza monster, set on finding and eating you for sustenance before you ever have the chance to eat another slice of pizza yourself... which is exactly your goal.  Good, succulent, and life saving pizza also exists in the backrooms on this level, and it is your mission to find and enjoy it before you happen to be enjoyed by... something else.
