Goal: Drill as deep as you can. Collect valuable ores. Return to the surface to sell and upgrade. Don't run out of fuel.
Movement: Use A / D or arrow keys to move left/right. Hold SPACE to use your thrusters. Flying uses fuel rapidly.
Drilling: Move into tiles to drill them. Harder materials drill slower. Your drill heats up — if it overheats, you can't drill until it cools.
Cargo: Each ore takes one slot. Heavier cargo slows you down and increases fuel use. Return to the surface to sell.
Surface / Shop: When you touch the surface platform, you auto-refuel and repair slowly. Press E to open the shop and sell ore.
Hazards: Lava damages your hull. Gas pockets explode when drilled. Falling boulders can crush you. Fall damage is real.
Depth: The deeper you go, the rarer and more valuable the ores. But hazards increase too. Bring a good rig.
