This mod adds (as of now) 30 blocks to the game. Through these blocks, you can combine cobblestone, dirt, sand, and soon to be more, by placing them side by side in a crafting table. This will get you the second version of the block. Place two V2's next to each other in a crafting table, and you get a V3. Versions go all the way up to ten, which is a range of 20 (Vanilla Block) to 210 (Compressed Block 10). That's 1024 blocks in one!
