Dirt

Dirt is a block in the game Concrevival.

History
Dirt was added before alpha, it was placeable while the stone wasn't. A variation of the block, grass appeared on the title screen.

In Closed Alpha, Dirt would generate in every new world in 3 layers. The grass variation appeared on top of that.

It has been announced in a Weekly Nextend Blog Post that after a period of time, grass will grow on an exposed dirt block. Similarily, a covered grass block will become a dirt block after a short time.
