        // Currently it's very hard to properly deinitialize Godot on Android to restart the game
        // from scratch. Therefore, we need to kill the whole app process and relaunch it.
        //
        // Restarting only the activity, wouldn't be enough unless it did proper cleanup (including
        // releasing and reloading native libs or resetting their state somehow and clearing statics).
        //
        // Using instrumentation is a way of making the whole app process restart, because Android
        // will kill any process of the same package which was already running.
        //
