This Game is so Great, That Im Literally Grinding Coins, But Its Hard To Get The Gems Like Maybe When You Need Gems, Maybe Add Gem Miners So That we Can quickly get gems, Also On The Gem Miners, When Their Level 10, we will get 2 gems everytime they mine, And then level 20, they get 4 and level 60, they get 10 gems, the gem miners needs to be slow so it will be fair, Anyways I Love the Game!
