‥∴ Bringing the Allure of Goldfish Closer ∴‥
This app is the culmination of the developer's childhood dream: to bring the beauty of goldfish to life through programming. After 15 years of development and refinement since the release of the previous version, "Wa Kingyo," this app strives to reproduce the elegant and charming behavior of goldfish. From the gentle movements of their fins to the pursuit and munching of food, I hope you feel the enchantment of these captivating creatures.
