Minerals and upgrades!

Hi folks!

I've just published an update for Strip Mining that adds various kinds of minerals, all with different values, for you to find and collect so that you can upgrade your stats. There's coal, iron, gold and diamond, each with its own value.

By collecting them you earn cash, so you can run back to the shop and upgrade your mining power, your mining speed or your running speed.

Thank you very much for supporting us, please let us know what you think of this new stuff!
