What is FinCrementalOS?

This single-player, 2D incremental shooter puts you in a submarine, firing a cannon at fish and selling your catch to fund upgrades and unlock new species and areas. You manage the business through movable computer windows that also obstruct your firing space, while emails reveal a conspiracy involving your submarine.
