Use the cursor keys to move Sam around. When not moving, you can press the spacebar to fire your Electro-Spear and stun your enemies. Keep stunning them for long enough, and they'll give up the ghost! You can also kill enemies with rocks: tunnel underneath them and try to squash your enemies as they fall. Don't let the enemies touch you, and watch out for the dragons' fireballs.
Sam gets an extra life for every 25000 points he scores - collect the bonus gems, coins and treasure chests for extra points. Press S to turn the sound effects on or off. Press M to turn the music on or off.
Dig for victory!
