About this game
How it plays
- Drill down, drive sideways. Hold ↓ to cut down, ← or → into a wall to dig sideways, ↑ to lift off. Or hold the mouse where you want to go.
- Don't run out of fuel. It refills at a depot, it drains even while you idle, and running dry away from a shopfront ends the run. No rescue crew.
- A full bag is heavy. Worse lift, roughly double the climb fuel when full, reported as a percentage and a mass. Press J to jettison your cheapest ore when something better turns up.
- Ten strata, ten minerals. Slop Shard at the top for 15, Lore Diamond near the bedrock for 12,000.
The surface strip
- ⛽ ALPHA DEPOT: fuel.
- ⛏ BETA PROCESSING: where you sell your ore.
- 🔧 GAMMA WORKS: hull repair.
- 🔩 DELTA OUTFITTERS: upgrades, explosives, and the three things you can use underground. A Spare Jerrycan, a roll of Flex Tape, and The Yeeter.
There is a fifth shop somewhere.
Three ways to dig
🔓 Dig!: a fresh mine from a fresh seed.
📅 Daily: one mine, the same for everybody all day.
⚔️ Duel a friend: the same seed, live, and the richest banked haul wins. A shared seed equalizes the mine, not the run: same Lore Diamond in the same tile, and only one of you still has the tank to be flying when you reach it.
