Needs work – Mine Upgrade Review

I am a huge fan of idle games. However, this game lacks a major part of being idle: accruing resources while the app is closed. The idea of the game isn't terrible. Also, if the exact benefits of upgrading a unit was more clear that would be helpful. It wasn't obvious that speed doesn't stack, you don't get more workers, you just increase the capacity of each one. With some minor changes this game will be smoother and have room for some updates that extend gameplay.
