Each level in the game is made up of rectangular blocks, and contains various things including treasures, enemies, locked doors, bonus items and traps. P. P. Hammer carries a jackhammer, which allows him to drill through a block he's standing next to. As in "Lode Runner", drilling through more than one layer of blocks requires creating a triangle-shaped cavity more than one block wide, and blocks reappear after a short while. A block reappearing on top of P. P. Hammer kills him.
