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).
