Mr. Driller returns to handheld format, as he brings his puzzle-solving, block-drilling ways to the Nintendo DS. In Mr. Driller: Drill Spirits, you control our hero as he makes his way deeper and deeper into unknown caverns, knocking out blocks of different colors while avoiding getting squashed and picking up precious oxygen pills to keep him alive. This is the brightest Mr. Driller game yet, packed with tons of stages to complete and modes to challenge. You won't have to dig too far for fun with this game.
