The game play feels pretty relaxing. Art is fantastic and I like the concept. I think the controls are a little cumbersome on mouse but would work great for mobile. I don't really understand the choice for screen wrapping. If you revisit this maybe add the surface of the water and have the narwhal breach the surface. There could even be rewards for doing so. I think this is a really good start to a game that has a lot of ways to expand upon it. Great work!
