Good luck!

Here’s a c# version of a Quit button.

  void OnGUI(){

     if(GUI.Button(new Rect((Screen.width) /2, (Screen.height)/2, 50, 50), "Quit Game")){

       Appliation.Quit();          


}
}

This is the verson where you press escape to make it quit.

void Update() {

 if(Input.Getkeydown("Escape Key"){
   Application.Quit;

}
}
