You play as Susumu or Anna in Mr. Driller 2 , equipped with just a pressurized suit and a drill. Your goal is to reach the King of the Undergrounders by drilling down thousands of feet while avoiding being crushed and managing your air supply.
The game is a real-time puzzle where you'll move down or sideways in an effort to reach the bottom. As you dig, blocks will fall into place, but some colored blocks can stick together temporarily, giving you time to rest. However, if 4 or more blocks come together, they'll disappear and cause chain reactions that can become deadly quickly.
The game features three modes of play: Story Mode, Time Attack, and Endless Driller. In Story Mode, the gameplay is straightforward as before. Time Attack offers a set number of levels with a specific time limit to beat. Endless Driller allows you to dig as long as possible without running out of air.
