Level 6 is the worst it's just dark place and I hate the dark

sorry yall i wasn't that informed about the backrooms at the time I made this

Level 374 is a level that's pretty disturbing in my eyes. Or at least it was until it was Nerfed. Originally it was a Deadzone-Class level that was essentially a slaughterhouse that butchered humans into various meat products, and even forced them to breed to keep the product flow consistent. Now it's a Class 3, various entities get butchered, but it's still dangerous for humans.

The shady grey is worse than run for your life

You are granted infinite energy when running away from the entity biomass in level !, the main danger is tripping. If you weren't and still had to run the, what, 10 kilometers, then I'd say it would be worse than THE SH4DY GR3Y, but you cannot be sent to it more than once since by now you have proven to survive one of the most dangerous levels in existence, which would push it behind the 64-bit integer limit level, as it is theorized you can escape the backrooms through it. A tradeoff from the frightening part of a truly infinite staircase, and you are also granted infinite energy to climb those steps. The End..? Is a level with illusions of reality, with computers that are hangout spots for partygoers, which these 2 put together would tbh make it worse than level 42, which is literally an eternal wait. All of these levels are horrific and we are all amazingly lucky they don't exist (hopefully lol) and anyone who came here from reality without knowing how it works would freak out fast. The levels I'm not really informed on in this list are below:
256
-81
