Side Details
You will have contact lenses until the end of the level, and even attempting to take them off will kill you instantly.
Only one person can be in Level 99123 at a time.
Description
Level 99123 is the 99124th level of The Backrooms, and it can only be described as a complete nightmare come true for claustrophobes.
Level 99123 looks like a typical modern skyscraper, but with much more danger, it is an enormous 25-story, tower themed escape room. As soon as you gain consciousness, the first thing you will notice is a holographic timer on your contact lens, counting down from 6 hours, 15 minutes, and as soon as that timer is over, a giant laser will obliterate the entire building, as well as anything in it. (which is also noted on your lens)
When the timer starts, you will be on the top floor and a bunch of stuff (from wooden chairs to paintings from The Frontrooms) to and a hidden key will spawn in every floor, randomly placed, but increasing in complexity the further down you go. The stuff will always be randomly placed but the stuff itself never changes.
When you find the key you can use it to unlock a door to the next floor, which will have a completely different layout to the last one.
Entrances
Holding any Level Key while exiting Level ! has a percentage chance of the first two digits of entering Level 99123. (for example, a Level 3999 key has a 39% chance of bringing you to Level 99123 by exiting) If you are holding more than one level key, the one with the highest number level will be favored for the odds.
Going into a building that says "Escape Room" in Level 11 will bring you to Level 99123.
Putting on contact lenses in Level 6 has a 10% chance to bring you to Level 99123.
Exits
Completing the "Escape Room" will lead you to either Level 11, or Level -18.
Somehow noclipping through the laser once the timer reaches zero will bring you to The Laserscape.
Jumping out of the window towards the floor below will take you to Level 998.
Going through the window, climbing to the roof and noclipping through the spire of the tower, or noclipping through a painting will take you to Level -1.5, but when you noclip through through the paintings, there is a small chance to lead to level 3000.
