Delve deep for greater treasures, but also face increased dangers.
Mining productivity research, will overhaul your mining equipment,
reinforcing your pickaxe as well as increasing the size of your backpack.

Breaking rocks is exhausting and might make you hungry.
So don´t forget to eat some fish once in a while to stay well fed.
But be careful, eating too much might have it´s consequences too.

As you dig, you will encounter black bedrock that is just too solid for your pickaxe.
Some explosives could even break through the impassable dark rock.
All they need is a container and a well aimed shot.

Darkness is a hazard in the mines, stay near your lamps..
