I like the concept but it's completely ruined by 2 things; 1. The number of advertising is insane, sometimes just to load the app you need to watch one. Other times it gives you a choice to watch an ad for a bonus, you click no.. it's shows it anyway?!?! 2. No flexibility in the upgrades. The game basically forces you to upgrade all of the drilling parts simultaneously or the unbalance makes everything not really work. If you don't have flexibility here then there is no depth. Pun intended.

Game is interesting and well done, however there are some things that just makes me not want to play (and actually lead to uninstalling). - Wheel spin is placed in the worst place possible, in the most used space of screen when collecting gems. It could at least go away when I open it and then close it. I am not interested in spinning it, but it covers very valuable space. It's done well with Iron chests and Rockets while digging. Clicking on them will prompt to watch an ad for a reward, closing the offer chest is gone and no longer in the way. - Taking a reward from a quest requires to watch an ad... WHY? - Notification on clan menu... I don't want to join or create a clan, but this notification is constantly showing up... - Why does shop have a `!` on it, I may not want to buy any service right now. And it's just annoying. Never the mind the notification it has when daily reward is available. AT THE VERY BOTTOM OF ALL PURCHASE OFFERS!

I would have been perfectly fine if the game never evolved beyond its core gameplay. What I was not prepared for was how ever increasing amounts of your screen get cluttered with ads. Click on them, even in error, and they expand, which makes you lose even more of your screen. There's a sort of mini game shoe-horned into the game after reaching a certain depth. I say sort of mini because while it's roughly equivalent to the main gameplay in terms of depth (which is pretty shallow) you can only play one round every 2 hours. Frankly, this thing is really more of a sophisticated ad than a game
