Neat to see another game that doesn't just reverse the roles once, but keeps switching them around!
The atmosphere of the game is really good and I do like that when it's dark, you need to actively search for the fish, but when it's light and the fish can hunt you, you can clearly see where the fish are.
A small issue I had with switching between hunting or being hunted is that, when I was hunting and the hunting phase ended, I'd usually be with quite a lot of fish and I'd immediately take damage. I think it would be nice if there was a little warning that phases were going to change, or a small period of immunity when the fish start hunting you!
Still, I do very much like the art of the game - I love cyan/purple/pink colors and this game fits that need exactly!
