I enjoyed the bubble popping sounds and like managing the aquarium. Having more upgrades would be nice aside from the tank size. Each fish growing up was surprising to see so I looked forward to that. The BGM loop was a bit short for a game where you do spend quite a bit of time in. I tried muting it but that also muted the sfx. I think UI wise, some more responsiveness when things are clicked and knowing what you're hovering over would be helpful.
