Must a Mine

We get gold and other valuable metals underneath the ground.   We use this metals on all sort of things.  That is why; we keep on digging.  The mining companies makes the most money, but we don't care as long as we are getting part of it.   The game is played via mouse and this game concentrates on digging.  You need to build different kind of workers to dig for you.  You need to unlock them first.  You can upgrade them with gold.  As your worker level up, you can unlock some new skills for them.  All of these are needed to dig for more gold.
