Arrow keys to move, z to mine. Explore the cave to gain points. A mining a wall gets 1 point, a stalagmite 10 points, and finding a mushroom gives 100. If you mine out of the room, you should find another cavern, continue to find more and more caverns, racking up the points. I had allot of fun making this entry, procedurally generated caverns and all, so I hope you have some fun playing it.
