Mr. Driller (Japan)[Hi] - Gameboy Color - Puzzle

Mr Driller's world has been covered with mysterious blocks. Armed with only a mighty drill, you'll have to dig your way down to safety before his air supply runs out! Mr Driller is a real-time puzzle game that relies solely on quick-thinking and a bit of planning. Gameplay is a combination of Tetris and Boulder Dash: You have to drill down through multi-colored blocks to reach the bottom while avoiding the consequences of reckless drilling (blocks may fall on you and crush you).
