    // Delays quitting for 2 seconds and
    // loads the finalsplash level during that time.

    float showSplashTimeout = 2.0f;
    bool  allowQuitting = false;

    void Awake()
    {
        // This game object needs to survive multiple levels
        Application.DontDestroyOnLoad(this.gameObject);
    }

    void OnApplicationQuit()

        // If we haven't already load up the final splash screen level

            StartCoroutine("DelayedQuit");
        }
