Full instructions: Player is invincible at start of level (when he is flashing). Shallow holes (less than three digs deep) will only slow a Snark down. If a Snark is left in a deep hole for too long he will climb back out as a meaner Snark! Meaner Snarks must be dropped through more than one level. Snarks can be dropped on Snarks to squash them. You can walk over a Snark that is in a deep hole (but so can other Snarks). Extra life at 10,000 points.
