Cute little game with pretty impressive aesthetics. I watched my girlfriend play it and we didn't really notice any meaningful impact in what she chose to add to the aquarium. I wonder if the water quality system is even necessary or if this could just be a chill cozy game with zero pressure (though from my experience with aquariums when I was younger, water quality management is a pretty huge part of having an aquarium, so maybe you shouldn't remove it :D).
