Probably the worst and most one dimensional tycoon game I've ever played. All do you is mine things in order to build more mines so you can mine more things. That's all there is to it. There are a lot of levels, and it would take years to finish the game, but it's so repetitive and doesn't sufficiently engross or distract me from my tedious existence. Gaming should be fun, exciting, and challenging. This game is none of these. It's well made though, so hats off to the devs.
