Control Mr. Driller as he drills down through myriad worlds buried under colored blocks. Two big challenges face players in Mr. Driller as he digs. First is the imminent danger of an underground collapse as the blocks begin to stack up on top of our little hero. Players have to link up same-colored blocks in order to form a protective ceiling above Mr. Driller before a cave-in turns him into Mr. Pancake. The other big danger is running out of air.
Mr. Driller has to find oxygen canisters during his descent in order to protect his air supply. The only problem is that air can be hidden in some of the most dangerous areas of the puzzle.
