Astro Tycoon is a space mining simulation game where you land on alien planets, vacuum crystals out of layered terrain, sell them at your base, and reinvest every coin into upgrades that let you dig deeper and earn faster.

Each expedition is a self-contained run — carve tunnels, fill your backpack, return to base, upgrade, repeat — and the loop tightens as you unlock stronger tools, hire workers, and automate your operation.

You start as a lone miner with a basic vacuum gun and a small backpack, landing on the surface of an alien world filled with crystal deposits buried under layers of destructible terrain.

The core gameplay is satisfyingly direct: move across the planet, aim your vacuum tool to mine crystals, fill your backpack, then return to base to sell everything and spend the earnings on upgrades. What creates depth is the upgrade tree.

Three stats drive your progression — force (mining power), capacity (backpack size), and speed (movement) — and knowing which to prioritize per planet changes how efficiently you operate. As you advance, you unlock new planets with rarer minerals and tougher terrain, hire workers to automate basic collection, and build mining machines that generate income while you explore deeper.
