As a non-pet lover, I can now enjoy some of what goldfish have to offer. The visual is great, and the developer also makes it quite customizable. I can say that this app is not only the culmination of Mr.Hakozaki's dream but also the idea of my dream to have a lively and visually striking simulation in my apartment coming true! I have it up continuously on my second screen of my Mac in my room whenever I like for hours. I fine-tune the visual settings in a way that minimizes its usage of computing resources while still looking really nice. Thank you for creating this and sharing it with the rest of us. I really appreciate it.  To Mr.Hakozaki, I have a request: For my setup, I have my M1-Pro Mac connected to an external display and put RYUKIN in fullscreen mode. It currently has side black stripes to fill the 16:9 ratio of the monitor, so it will be better to have the app run in a screen-ratio-agnostic way. I know that the app is iPad-based, but I've already seen some iPad apps from the App Store that is resizable to some varying screen ratio. Please consider developing this feature if you can pursue it easily. -- Mys.
