Blockus is a mod made using Fabric API. It adds blocks of several types.

Most of the blocks require a stonecutter to make them. I recommend the use of a mod like Roughly Enough Items (REI) for all recipes.

NeoForge support is currently not planned. You can use Sinytra Connector for NeoForge support.

Some added blocks :

Naturally generated things

Limestone is generated between y = 0 & y = 128 but much less between y = 64 & y = 128
Marble is generated between y = 0 & y = 64
Bluestone is generated below y = 0
Viridite is generated below y = -16 & more frequently in Deep Dark.
White Oak Trees are generated in Forest, Dark Forest, Flower Forest & Plains.
Rainbow Roses spawn in Flower Forests & Meadows
