Ratings and reviews

a simple idle game that makes my phone run much more warm than it should. So, presumably, it still needs optimization. ads will try to fly under your fingers while you play.

after tapping to start mining, a graphical glitch occurs where the entire screen flashes blue in an upsetting fashion. the game is unplayable

it's a bit slow but not a bad game
