| GameScreen | A screen is a single layer that has update and draw logic, and which can be combined with other layers to build up a complex menu system. For instance the main menu, the options menu, the "are you sure you want to quit" message box, and the main game itself are all implemented as screens. |
| ScreenManager | The screen manager is a component which manages one or more GameScreen instances. It maintains a stack of _screens, calls their Update and Draw methods at the appropriate times, and automatically routes _input to the topmost active screen. |
