OneBlockChunk is a mod, designed for Baablu.
Each chunk is made up of 1 singular type of block. Explore the world but be careful, you may enter a chunk you did not expect to encounter. End Portal Frames and Spawners remain untouched so you can still beat the game :)
Use Fabric and put the mod in mods folder!
