The core gameplay involves drilling downward through a grid of colored blocks that make up the earth while constantly monitoring and managing a depleting air supply. The deeper the player descends through the layers the higher the point total becomes as more points are racked up the farther you go. The game incorporates strategic elements similar to tetris where clearing matched blocks and creating chain reactions provides bonus points and higher scores. The original review highlights that this is a puzzle game with drill down mechanics where the farther you go the more points you rack up and it contains tetris like strategy to gain more points. The review also emphasizes the critical need to remember to keep that air up throughout the descent. Players must carefully plan each drilling action to prevent block collapses from trapping the character or cutting off oxygen supply. The objective is to reach maximum depth while maintaining enough air to survive and using the tetris like clearing mechanics to optimize the score before the air meter depletes completely.
