Move your character around the screen to find the way to the exit. Each time you push the arrow you either move one square in that direction, or you use an item such as a shovel (break through rocks beneath you) a pickaxe (break through rocks to your left or right) or up to create a ladder. Each of these items can only be used if they are in your inventory and only once per item. Collect keys to open doors and the more tools you get the more points you score.
Subsequent games added a lethal caterpillar (2) and coins and gems that could be found, along with upgrades that could be purchased with coins (3).
