The Lost Levels is a Backrooms-inspired horror and exploration mod that adds several liminal dimensions to Minecraft.
Instead of entering through a portal, you can accidentally noclip out of reality by flying into a wall, falling in the wrong place, or running into a wall. Once you enter, you will need to explore each level and find a way out.
A huge maze of yellow rooms and hallways filled with buzzing lights. The area is confusing, repetitive, and easy to get lost in.
A large network of tiled rooms, flooded hallways, and indoor pools. Some areas are calm and open, while others are dark, cramped, and much deeper than they look.
A quiet neighborhood with repeating streets and houses. The roads can loop back around, something may be watching you from inside the houses, and making the wrong choice can reset your escape progress.

Once you are inside, finding the exit is up to you.
