-A slightly more complex example is the game controller of my [Flappy Bird](https://github.com/armin-reichert/birdy) game implementation.

+## Example 4: Pac-Man ghost "AI"
 
 I used this state machine library extensively in my [Pac-Man game implementation](https://github.com/armin-reichert/pacman), which in fact was the main motivation for creating this library at all. In that implementation, state machines are used all over the place: for the central game control, for Pac-Man and the ghosts, for their movement, for controlling the animations in the intro view and more.
