Each cave is viewed from a fixed top-down perspective. Rockford must collect the required number of diamonds and reach the exit before the timer expires. Dirt can be removed by moving through it, while empty spaces allow boulders and other objects to fall.

Caves are arranged as separate levels with increasingly demanding layouts. Fireflies and butterflies patrol enclosed areas, amoebas can spread through open space, and falling objects can create chain reactions. The player has no conventional attack system, so survival depends on digging, timing, and using hazards against one another.

Plan the route before disturbing large groups of boulders. A single dug tile can change several falling paths, so avoid trapping Rockford behind rocks or enemies.

Collect only the diamonds needed to open the exit when the timer is tight. Use boulders to crush creatures, and remember that chain reactions can be safer and more efficient than direct movement.

• Leave an escape route whenever possible.
• Watch falling objects from above before entering a tunnel.
• Use the cave walls and narrow passages to control enemy movement.
