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?

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.

Not a game, all you can do is click to build something then wait for your workers to slowly build it. That's it. I persevered with completing the first platform but after that I just got to move to a second to restart the process. Just seems like an ad revenue generator to me (not that I saw any, being on an ad-blocked network).

Enjoyed building the 1st space station. I finished it, unlocked 2nd station. Then the game goes all wrong. All resources u earned while working on 1st station. e.g more people to build, more researchers & all the money u accumulated that u need to be able to upgrade the 2nd station, is all gone ! It's like you're starting the game over with just one person to build again, but the worst thing is now the cost of upgrading staff is higher. it's at a level it got too when u finished 1st station !!!!
