You play as Mr. Driller. Drill your way through the earth's crust, avoiding falling rock along the way. You have an oxygen meter that is going down at a steady rate, and can only be replenished by the air capsules scattered underground. You must also avoid breaking brown rocks labeled with an "X," at the cost of air. For effective drilling, drill through blocks touching like-colored blocks. Blocks that have no blocks underneath them, and are not connected to a similarly colored blocks will fall, leaving you with a case of the dead-sies if you happen to be in the way of its gravitational pull.
