Now, you're ready to export the game into an executable application.
On the Unity main menu, choose File > Build Settings.
Select the Add Open Scenes button to add the scene you just created.
By default, you'll see that the Platform is set to PC, Mac & Linux Standalone on the left. You can change the Target Platform further to choose the machine you're trying this tutorial on. When ready, select the Build and Run button. Save the executable application to your Desktop.
The build process starts.
If the build process was a success, you should see the application running with the rotating cube. Press Alt+Enter to exit full screen.
