You play as an oil-mining robotic arm, extendable down into the depths of the earth's crust to extract precious oil and fill your pockets. However, beware of the terrifying creatures lurking in the shadows – should they come into contact with your robotic arm, you'll lose a life.
The gameplay revolves around navigating this robotic arm through increasingly difficult levels, avoiding deadly traps and monstrous bugs while collecting as much oil as possible. As you progress, the terrain becomes more treacherous, with new obstacles and challenges appearing around every corner.
