Astro Tycoon turns planetary exploration into a tycoon loop. 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.

The game runs as an HTML5 browser game on PLRun, loading instantly on desktop, tablet, or mobile. If you enjoy idle tycoons with active decision-making, Astro Tycoon strikes an unusually good balance between hands-on play and automated growth.

Move your character using Arrow Keys or a directional joystick on mobile. Your vacuum gun aims automatically toward nearby terrain and crystals as you move — on desktop, you can also aim with the mouse. Press Space to activate abilities like the jetpack when available.

Press E to interact with objects, portals, and base structures. Left Click opens the mission log, and Right Click accesses upgrade menus and base management shortcuts. Walk your miner into the terrain to begin vacuuming crystals.

Your vacuum gun destroys blocks of rock and soil, sucking up any minerals embedded in them. Crystals come in different colors, and rarer colors yield higher sale prices at base.

Your backpack has a fixed capacity — once it fills up, a visual indicator alerts you, and you need to return to base to sell. The sell transaction is instant: walk into the base zone, resources convert to coins, and you can immediately spend those coins on upgrades.

Three core upgrades govern your mining efficiency. Force increases vacuum gun power, letting you break through tougher terrain layers faster and access deeper deposits.
