In this sequel to the 1984 classic, players set forth as Rockford or Crystal and mine their way through a variety of hazardous, yet stunning, three-dimensional caves. Explore the 100 caves and collect the right number of diamonds, while avoiding boulders and enemies to unlock the exit. But hurry – the clock is ticking! The difficulty increases with each new cave and more enemies and challenges will emerge as you progress. After completing a cave successfully, a green checkmark will appear next to it in the cave list. If you complete a level perfectly, a gold checkmark will appear. Can you master the power-ups, transform boulders into jewels, squash enemies, and get to the exit before time runs out and without becoming trapped?
