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?

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.

games good with the no ads pack, without its really slow edit:After playing a bit, even without ads, it's mostly waiting. the bonuses are amazing, and timing on them coming in is fine. however, needing to keep reapplying the extra crafts really is annoying, and it doesn't notify you for upgrades unless you have free craft slots. still a fun game, but more "I played for five minutes" type. edit 2: game stopped working. payed for packs, got to the second level and it no longer loads in.

So I purchased the no ad pack on the first station & it was a good game to pass the time. Bonuses are good. I've been playing for about 3-4 weeks everyday & the stations are never ending. Completing 2 stations everyday. It's the same thing over & over. I don't know how many stations this game has but I don't want to find out. I got bored playing.
