I liked the vibes and music. The fish swimming animation is top notch and I like how the fish's mouth opens in anticipation of the pellet going in, and you even see the pellet going through his body. Very immersive animations.
Also loved the description: You are a fish. You eat pellets. Life is easy. simple haha. Being able to see the storm would be nice but I understand it was scrapped. Nonetheless it ended up being a peaceful relaxing game which is not a bad thing.
