Blockrooms

The Backrooms in Minecraft! Access 2 iconic Backrooms levels via specific portals. For level 0, make a 6×4 (Nether portal shape) portal out of yellow concrete. When lit, it will teleport you to the infinity of yellow rooms, halls, and dead ends. For the poolrooms (lv. 37), build a portal out of sea lanterns. Watch out for the dangerous entities that spawn in the halls of these rooms, from the smiler to the partygoer. Though some may resemble mobs you already know, be warned: They are MUCH more powerful. In villages around the map, you can uncover the Yellowed, a villager who delves into the backrooms to sell products from within the labyrinth. To enjoy this plugin, I suggest using the included texture pack; it will make the entities look different than their overworld mob counterparts. Random events can also trigger noclipping into the yellow halls. Pearling, void death, fall damage, and suffocation all have a chance to throw you into the Backrooms. If you die in the Backrooms, you have a good chance of waking up in Level !, where, if you survive the horde, you can avoid death.
