GeoDepths is digging and smelting, but good

What a great little thing. You've surely seen a hundred post-Minecraft games about building a base to smelt iron to build a base, and probably even thought to yourself that they look entirely fine but kind of... redundant? There's only so many times you can walk back and forth from a cave to a forge.

But what if instead of trudging around a grey cave, you were driving a big drilling machine instead? It's so simple, and yet it makes all the difference in GeoDepths.
