Press ENTER to START game. Use ARROW keys to move. SPACE BAR to JUMP. GAME OBJECTIVE : There are 20 caverns, and inside each one, are several flashing objects, which you must collect before Miner Willy's oxygen supply runs out. Once you have collected the objects in one cavern, enter the flashing portal, to take Miner Willy to the next cavern. Avoid ALL enemies, the Poisonous Pansies, Spiders, Slime, and the nastiest of all, the Manic Mining Robots. Miner Willy can also be killed by falling too far, so remember to time jumps to avoid death. Extra lives are given every 10,000 points, and the game ends when the player either runs out of lives, or completes all 20 caverns and escapes to the open air above. Good Luck !
