Strategy & Simulation
#Mobile-Friendly#3D#Browser Game

You're an astronaut on a tiny moon base. Walk over glowing crystals to mine them, carry them to the Refinery and sell them, then pay for bridges to new asteroids with more valuable crystals. Hire robots that mine for you, buy upgrades, race to fill shuttle orders before they fly off, and dodge meteors that knock half your load away. Save up for the rocket and launch it to complete the mission. A 3D game for keyboard, mouse or phone, built for you by Codex from one prompt.
