About game
Your starting oxygen tank lasts 40 seconds! Break through rock to find copper, gold and crystals. Choose whether to bank your loot or risk one more chest. Upgrade your pickaxe, backpack and air tank at camp. Each tank upgrade adds 5 seconds. Restore lift stations and explore deeper. Discover three layers of the mine, collect six relics and reach the treasure vault 100 meters underground. Every expedition generates a new map, and your progress is saved automatically.
How to play
Tap a block beside an open tunnel to walk over and dig. Tap an empty cell to move there. On desktop you can also use the arrow keys or WASD. The “To the lift” button starts the return journey along an open route, which also consumes oxygen. Bring your loot to the surface to earn coins. If you run out of oxygen, the rescue capsule returns you home without that expedition’s loot. Buy upgrades in the camp workshop. Use the pause button or Esc to pause.
