1. Inside that method, add the following lines to create our Label object:

   _tutorialLabel = Label::createWithTTF("", "fonts/Times.ttf", 60);
   _tutorialLabel->setPosition(Vec2 (_screenSize.width *  0.5f, _screenSize.height * 0.6f) );
   this->addChild(_tutorialLabel, kForeground);
   _tutorialLabel->setVisible(false);

2. We add four states to our enumerated list of game states. These will represent the different steps in our tutorial:

   typedef enum {
     kGameIntro,
     kGamePlay,
     kGameOver,
     kGameTutorial,
     kGameTutorialJump,
     kGameTutorialFloat,
     kGameTutorialDrop
   
   } GameState;

   The first tutorial state, kGameTutorial, acts as a separator from all other game states. So, if the value for _state is greater than kGameTutorial, we are in tutorial mode.

   Now, depending on the mode, we display a different message and we wait on a different condition to change to a new tutorial state.
