‥∴ Bringing the Allure of Goldfish Closer ∴‥
This app was born from a childhood dream of recreating goldfish through programming. Fifteen years after the release of the original app *Wa Kingyo*, countless refinements have been made to capture the graceful and charming nature of these fish. From the gentle movement of their fins to the way they chase and munch on food, experience the beauty and warmth that goldfish bring.
