I really like the concept of the game! Raising fishes as gacha capsule to see what they could become was exciting. A nice polished experience overall. Though the notification text pop-up and music could be tweaked a bit as they started to bother me the longer I play.
Other than that, it's still a banger of a game! Would love to see upgrade system that can automate some mechanics. Maybe an auto-feeder or bubble collector?
Great work!!
