In this chapter you added many interesting features into your game to almost prepare its final version, which will be submitted to the store. You learned how to save and load the current state of the game to be able to resume it from the last level. You also added audio support, both for the background music, which is being played all the time while the application is running, and sounds played in particular situations.

The current version of Space Aim 3D supports not only audio recordings, but also video clips, as well as vibrations that can improve the experience by indicating important situations during the game. Your application is also equipped with the mechanism of speech recognition and synthesis, thus you can easily choose options in the main menu by saying their names. You learned how to synthesize the text, thus the application can "tell" something to the user, as well. At the end of this chapter, you temporarily disabled the lock screen and it will no longer distract the game.

Currently you can start the game, test all newly added features, and think about information that will be published during submission to the store. You are close to the moment when your first game will be sent to the Windows Phone Store!
