A work-in-progress datapack that adds a few new dimensions, all of which are levels of the Backrooms. I originally made this just to have it on a server with my friends, and it's not meant to be lore-accurate.
When you die for the first time, you'll be sent to the Backrooms. You'll keep your items from the Overworld, but there's currently no way to get back out.
If you explore level 0 for a while, you might come across a room made of white terracotta that can take you to level 1. In level 1, there's a structure made of white concrete that can take you back to level 0, or to level 2 instead. I'll probably add more levels sometime later, but I don't plan on adding any mobs to the dimensions.
Please note that it can take a long time for the dimensions to generate. If the game gets stuck, be patient and it should load eventually.
