ModsJava
The backrooms, blocks and more
Java mod listed for Minecraft 1.16–1.20. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
A mod that has many blocks from the backrooms as well as a bunch of other items from the backrooms, this mod only has stuff from level 1 so far and doesn't have any mods.
(I will be doing 1 level at a time, each update adds a next levels blocks)
These blocks don't do any thing other than be not breakable so much won't change, they can only be obtained in creative mode currently and will probably stay like that.
