THE MAIN MOD IS IN THE FOLDER, PUT IT IN YOUR MODS IN GAME FOLDER WITH IT SO IT LOADS

SpacePotato's mod with my settings and built to just make a world, and be able to change the settings the way you want!

This mod adds in custom Shaders and camera effects using Veil and is not compatible with sodium or iris
The mod also has issues with integrated graphics and MacOS
Use Mod menu to access the config

Suffocating yourself in any way for long enough will eventually cause you to Noclip into the backrooms, where you have to travel through all 5 levels to escape:

Level 0 ---------------------- The backrooms we all know and love
Level 1 ---------------------- The Habitable Zone
Level 2 ---------------------- Pipe Dreams
The Poolrooms -------------- The Poolrooms O.o
The Infinite Grass Field ----- This one's different

The mod also adds four commands just in case:

/skinwalker <target>: Just in case the skinwalker refuses to spawn naturally, you can do this to have the skinwalker take the skin of your target. Don't tell anyone :D
/release <target>: Releases the target from the skinwalker if the target has had their skin stolen
/backroomsevent <event>: Manually triggers an event
/gimmemyinventoryback <target>: Restores the saved inventory of the specified targets from before they entered the Backrooms
/level <level>: Manually teleport yourself to a certain level.

Please report any bugs you may find to the GitHub Page

If the mod does NOT work, make sure you're following all of the steps below:

Download Simple Voice Chat and Geckolib. You do not need to download veil. It's already included
Do not use sodium or iris. This mod uses Veil which, in 1.20.1, is incompatible with either
Do not use Fabulous! graphics. Only Fast or Fancy
Do not remove Veil's deferred resource pack

Notes

The skinwalker does not spawn naturally in singleplayer. I really didn't see a point
There are a few bugs with devices that use integrated graphics and Mac OS
