The progression on this game is incredibly slow. The game feels good when you can progress fast, but when it takes anywhere from half an hour to 4 hours to mine, it's such a grind. They'd make more money if the game felt better & more fun to play. The events are ridiculously slow also. When you level up the deliveries, it feels good to get the boost, bity then the value drops off & goes back to a horrible grind again. There's a good game in here, bit it's mired by awful progression. It's a shame
