Funny, how we both had the idea of a digging game. ^^ Even the story.. (I know, it might not look like it, but I had the idea that my mole is an alien who can transform into animals, after crash-landing on a planet.)
Very cool atmosphere here, and the rotation of digging, fleeing from lava and upgrading made a nice gameflow. But sadly I've never seen one of those red minerals; and I was reeeally deep down there.
