This game sucks, for many reasons. First of all, you literally can't mute the game until you finish the tutorial. And even when you do, the sound toggle barely works. Be prepared for a constant humming noise, and occasional blaring notification sounds. There's ads constantly, you see ads more often than the game. All popups pause the game, which makes levelling up a BAD thing. Capacity upgrades also sabotage you, and truck count, the only one that matters, is orders of magnitude more expensive.

I liked the idea of this game but was very disappointed to see how often forced ads happened. I pushed through them to see if I liked the game enough to deal with them. After completing world 3, the game almost crashes and sends me back to world 1, which is still completed, and I can't do anything but keep mining and not even making money off it. Huge disappointment! Will wait for more updates and see if my review can be changed.

As many have already stated, you cannot ot progress through World 3. Just let's you collect materials and that's it; No buildings getting completed and no coins earned. Such a disappointment since I decided to go ad free. Hopefully the devs get these bugs fixed, but doesn't seem likely since these issues have gone on for months with no word from the devs on it.
