What is Dr. COG?

This free-to-play, single-player strategy game combines deckbuilding with visual novel storytelling as you restore a client's father's memories. During timed stages, you position clockwise- and counterclockwise-turning gears to meet memory-production targets. Clearing stages lets you add, upgrade, or remove gears from your deck.
