Additions[]
Blocks[]
- A new redstone component.
- Detects vibrations, and emits a redstone signal.

World generation[]
- A new underground biome.
- Made up of primarily dripstone blocks and stone, with large clusters of dripstone blocks hanging from the ceiling, pointed dripstone on the floor and ceiling, and many pools of water.
