Use the arrow keys on keyboard or the virtual joystick to move your miner. On mobile, tap anywhere on the screen to control movement. Drilling starts automatically when your character pushes into a block.
Drill ore, collect money, and buy upgrades. Glowing blocks are bonus blocks: they are tougher to break, but give more rewards. Bright colored glow means a bigger bonus.
You can upgrade not only your miner, but also the mines themselves. Better mines contain more resources, more valuable ore, character upgrade cards, extra oxygen, and cooling supplies.
Every level is procedurally generated, so each run is different. The farther you progress and the more you upgrade, the more rock types, bonuses, and rewards you will discover.
Some bonuses are unlocked through overall progress. Upgrade your miner, improve the mine, or do both — every few upgrade levels can open new gameplay features and extra options.
