Items not showing in Game mode

Trying to make basic 2d game with Unity.
I am also following some video lectures but having difficulties adding sprites or anything to the game.

Everything looks fine on Scene but the Game window is just blue...

What am I missing

 

Do you have a camera & if so is it facing your sprites?

 

If you are doing 2D, you might also want to set the editor into "2D mode":

This can be done anytime in the editor by clicking the 2D button in the Scene view:


Also, when you start a 2D project, you can set up the entire editor, including its defaults to 2D, by creating a "2D" project:


If you have not done any research, you may want to visit the "Learn" section of the website at:
http://unity3d.com/learn/tutorials

Here you will find great "getting started" material, including an introduction to the editor from a 2D point of view:
