You are the pilot of the unbreakable Driller. You have discovered a cave full of valuable gems but unfortunately it is inhabited by monsters! Ram into these monsters to launch your Driller up in the air and collect the gems. The key is to try to stay in the air and keep colliding with monsters to build up your combo multiplier. Your combo multiplier resets when you hit the ground. The goal is to earn enough points to move on to the next level before you run out of fuel.
