Backrooms don't have a limit on where you can be, every level has its own feeling, texture and entity. Out of millions of different levels its possible to find some of the weirdest things you have never seen. Every level has its power which can be either good or bad for you, so do these entities. To be said honestly, backrooms is still a dangerous place, not all rooms and entities are friendly, they can be quite evil and really robust, so when trying to fight one of them - your survival percentage well likely drops to 0.
I'm thinking you are familiar with this photo. Its the thumbnail for the American youtuber Kane Pixels famous "The Backrooms (Found Footage)" video, just flipped the other way around. This creature is something called "Bacteria" and is known for its disturbingly loud noise making and appearance. It has a power of super hearing but doesn't have any eyes, so it can't see but only hear, its also quite fast. When facing beings like these you wanna be as quiet as possible and wait until the monster walks by. If it happens to hear you - it knows your location right away and starts running towards you. You can outrun it, but also the creature's stamina is unknown.
Many beautiful levels belong to backrooms, so this level. Photo represents a level called "Leafy Corridors", and is known for it floating cities, goodness and the feeling like you're in heaven. If you happen to be there and look out one of the windows, then you'll be hit with this gorgeous day or sunset light - if you are injured, the light litteraly quickly heals you. On the ground is the grass with all its flowers - they give you feeling of relaxation and you don't have to worry about the bad things. Thats the power of this place.
This picture shows a place called "Foggy Avenue", and is known for its endless amount of roads, sometimes going in every direction. The primary colors of the place are blue and orange, but these can change over time, varying from any color. Usually the roads are about 100 kilometers in length, they can be also quite curvey which can cause a weird feeling in your stomach. Overall this whole level is just a bunch roads without any buildings, vehicles or signs of life, and the sky is often covered by a thick layer of fog - nobody knows whats hiding there. The fog makes it pretty hard to see any forward but you could navigate by the lightings coming from the lamp posts.
