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.

Unless I'm really missing something the game is just.. boring. You click ti start something and just wait until it's done. No offline progress for building and it takes like 10 minutes for them to build something. You also can't que up much even if it was trying to be an always on idler. Even if the ads weren't so in your face and sometimes forced I jusr don't see much of a game here.

I thought I would be fun. but when given the opportunity to watch an ad for some building supplies, I hit the watch button and was told the ads is not ready, to please wait, I waited 5 minutes and tried again , ad still wasn't ready. waited some more, again, the ad still was not ready. if they are not going to let the ad be seen. I dontbwant anything to do with their game.
