Quit splash screen not working

trying to setup my quit screen but cant get the input to work - the if statement isnt being picked up and im not sure why:

 if ((Application.loadedLevelName == "quit_screen") && (Input.GetKey (KeyCode.Y)))
         {
             UnityEditor.EditorApplication.isPlaying = false;
             Debug.Log ("Y Pressed");
         } else if ((Application.loadedLevelName == "quit_screen") && (Input.GetKey (KeyCode.N)))
         {
             Application.LoadLevel (loaded_level);
             Debug.Log ("N Pressed");
         }
