What a lovely game! Just taking care of my fishes! :)
The fish swim very smoothly, I like how they propel themselves and gradually slow down, like how one would expect a fish to move.
I genuinely just had a really fun time playing this game. It's one of my favorites so far. I quite enjoyed the chaos of spawning as many fish as humanly possible and becoming incredulously rich.
Fun surprises too! Like I did not expect a cat paw to come out of the middle of nowhere and abduct one of my poor fish
Kind of wish my fish visibly showed what their mutations were, but it's absolutely understandable if you didn't have enough time to incorporate that.
Sound design's really good too. The occasional bubble sounds, the fish splashing into the water, the muted menu sounds; it all adds to the immersion that I'm just watching fish in an aquarium. It's pretty relaxing.
