I suggest you find a way to invest in or—if you have the skills—modify the app to make it even better. You could add features like joystick customization and graphics settings (ranging from "very low" for budget phones to "very high" for high-end ones) to ensure smooth performance across devices. While it runs okay now, there’s always room for improvements—like adjustable camera angles or landscape mode options. Also, the joystick needs to be absolutely precise; right now, it doesn't feel quite perfect to me. Please check the Turkish text in the settings, too; I found two options there that I don't understand in my own language (Romanian).
You could take inspiration from top mobile games like PUBG or Mobile Legends—maybe make the camera angles more dynamic. Basically, the goal is to make the experience more enjoyable for players like me (server pros and myself).
