About this game

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?

what's the point in spending money to advance anything in the game when you don't get anything from finishing the station other than starting everything over from scratch and you can't even revisit your previous builds? so yeah, you build it faster but there's zero point to completing them. idle mode only earns resources but build queues do not progress at all so you literally have to sit and wait for everything live in the game.

I enjoyed the game. When I got to play it!! There is so many ads constantly. Not to mention it's very slow pace. It's a very slow paced game and when you get him with 2 to 3 ads watching your person build one part you will definitely be annoyed. There is many many ads. And there should be a way to upgrade your character. More people in game. Maybe some interaction and communication with other characters. But your guys wouldn't ever do that would you 🧐😂 These creators are wasting their talent.

This game looks pretty. but it is nothing but a vehicle for ads. Everything is automated, and the player controls nothing and does nothing except click on menus that lead to ads. Sometimes, refusing to watch an ad triggers an ad. Leaving the game idle triggers an ad, and progress does not happen when the app is in the background. In short, progress only happens with ads. The adds themselves are often 1 full minute long.
