An exploration game roughly in the vein of Flower or Journey. Play as a diver swimming through underwater caverns and submerged ruins. There’s no dialog and gameplay consists mostly of navigating a beautiful environment against an emotive soundtrack. The star of the show is the sea life - hundreds of real-world species of fish, turtles, whales, and more lovingly rendered with up to several thousand individual creatures on screen at any given time. The game sets up multiple jaw-dropping moments the first time you see certain animals or groups thereof.
