About this project

What does The Backrooms(legacy) add?

You enter through by jumping into the void in any dimension.
Creating a testing world is recommended to prevent corruption
If you find a glow item frame item on the ground report it in the discord
that is a broken exit and needs to be fixed
If you want to see my progress and plans click here.

What this adds:

This datapack adds The Backrooms which has alot of exploration content
This also adds advancements for every single thing in the backrooms

Why should i use this?:

this adds more exploration content and prevents you from dying to The Void while still having a penalty for falling into The Void

other info/bug reporting:

Glow Item Frames indicate an exit so look for those.
The bedrock floor is replaced with obsidian in every level so you can use that to get to back Level 0
The exit to the backrooms in level 0 being a long hallway with an exit at the end
The discord has a bug report channel so go there and there are books in every level explaining all information you need to know about that level

dont send your issue in general and install the resource pack
