About game
Your initial oxygen supply allows you to breathe for just 40 seconds! Smash through the rocks to uncover copper, gold, and crystals. Decide whether to deposit your treasures or take a chance on another chest. At the camp, you can improve your pickaxe, backpack, and oxygen tank. Each upgrade to the tank adds 5 more seconds. Fix the lift stations to delve deeper into the mine. Explore three levels, collect six relics, and reach the treasure vault located 100 meters below the surface. Every new expedition brings a unique map, and your progress is saved automatically.
How to play
To move to a block next to an open tunnel and start digging, tap on it. Tap an unoccupied cell to go there. On a computer, you can use the arrow keys or WASD for movement. The «To the lift» button initiates the journey back along the open path, which also uses up oxygen. Bring the treasures you've found to the surface to get coins. If oxygen runs out, the rescue capsule will take you home without the loot from that expedition. You can buy improvements in the camp workshop. Use the pause button or Esc to halt the game.
