The Main Menu Screen
You've already written many trivial screens for the previous games. Droid Invaders also has some of these.

The main menu screen presents only the logo and the Play and Settings options, as shown in Figure 12–4. Touching one of these buttons triggers a transition to the GameScreen or the SettingsScreen.
