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?

decent game. However, note, there are some flaws. I've noticed the listed required material numbers don't scale in the list. Also, sometimes the stats invested the builders and researchers carry over and other times they don't. Plus, I just noticed this today, but sometimes the prizes from the daily check in rewards don't carry over to new spaceships either, for example the spaceship that continually supplies materials but the robot will. Just a few notes

I got this game because of the ad. And a o's pretty much of a letdown, I thought there'd be a cool space game with building and battling, because we can agree or not. That if it's space it needs battles. Please add some battles or other mechanics to this game. I mean, for those players who live like afk or who don't mind sitting down and pretty much doing nothing for a little bit. This was the game for you. But people who like action don't get this game.

Played this game before and was hoping for a vast improvement from last time. Kinda disappointing that the graphics are mostly the same,the stuff to build is the same, and the only additional part I noticed is the meteorite research. No new material or events. When I made it to the third station I had no need for money because all my research was already done. Alot of work needs to be done to improve the game.Love the concept but disappointed by the lack of content.
