The game would get a 3 star for the fact that the gameplay mechanics behind it are fun, although extremely limited. Basic upgrades, mini miners barely breaks through any blocks, and gameplay gets too repetitive too fast. However, because of the sheer amount of advertisements, I give this game a 1 star. Upgrade drill? Chance of advertisement, Just drilling around? Chance of advertisement, Drill heats up and barely breaks through blocks? Get ready for more advertisements! Game is somewhat fun, but it’s a shame that it’s buried behind layers of advertisements
