A MASSIVE MULTIPLAYER MINING EXPEDITION
No download. Free. Play in browser. You start as a guest — save your miner anytime.
Prototype: every entrance currently leads into the same test mine.
On: wide chambers crack and cave in unless you line them, a fall can seal you in without air. Off: tunnels never cave in on you.
Regrows the whole world from scratch: every tunnel, fill and structure is gone. Coins and inventories stay; chest contents return to their owners. Type RESET to confirm.
