Welcome to Astro Builder, the ultimate casual idle game where you construct a space station in near-Earth orbit. Begin with a simple setup—a connecting ground track and a small platform. Material is transported to the platform via a space elevator and piled on the ground. Utilize the resources to expand and improve the platform, unlocking new equipment and producing valuable resources. Each construction phase reveals a new area, waiting to be developed and unlocked. Can you build the ultimate space station and conquer the cosmos?
