It is basically a "Breakout" clone - but with a "Digger Chan" theme. :) Digger chan, having made it down to the milk pipes that traverse the globe, often finds caverns with loose rocks hanging from the ceiling. They are way too unsafe for "M.O.O. Milk Co."'s other pipe engineers to work in, so you have to clear them. The only problem is that there are no ladders long enough. All you have available to remove these dangers is your trusty spade and a purpose-built rock-busting ball. Therefore, you have to destroy the precariously dangling rocks by using your spade to propel the ball into them! Remember that the engineers are very busy people, so if you fail three time you will be fired!
