Idle Planet Miner APK 1.21.2

5 stars: Need to add upgrades that can be repeated over and over again, even if it costs more each time. This would allow you to continuously upgrade, and not run out of upgrading. I'm talking in the science tree. For instance, the new plus one manager science upgrade. This would expand the game quite a bit.
5 stars: One day into it, and so far so good. Only issue is that the mining upgrade cost is out of proportion with the other two planet upgrades ( ship speed and cargo). Other then that it's a great game so far. Update: looks like it only out of proportion for the first few planets. Seems to be leveling out the farther you go. Thanks for the developer getting back to me so quickly.
4 stars: For an idel game it is okay. It doesn't require a pay wall to get started. The downside is that it only has a 2 hour of offline progress. As an active game it is slow. There are lots of unlockables, upgrades, and then rewards from watching ads are decent, and not forced. All and all I like it, and I haven't gotten through what feels like 10% of the content.
3 stars: Extremely well designed game from the bottom up, designer has a great sense of resource management tension. Ad watching not required but receiving bonuses for watching them is a nice twist. *edit* I have tried to play through the game multiple times and have lost my progress inexplicably every time.
3 stars: This is a decent idle game but the progression is pretty slow if you don't take the P2W options. The
