Boulders and Bombs

A group of spelunkers has been trapped under-ground on a strange planet. Your goal is to use a mechanical auger to burrow a tunnel from one side of the screen to the next to allow the group to get closer to safety. The escape needs to take place within a certain time, which is marked by the movement of the sun and moon. The fire button switches control between the auger and the fleeing human. Once all humans have been rescued, play continues in the next level or "quadrant".
