# Exercise: Game Over

In this exercise you will add a game over state to the game. After PacMan has lost all of his lives the game will be
over. PacMan should not respawn and the ghosts should stop.

The GameState class has the number of lives and they are already drawn on screen so that information can be used to
indicate the game over state itself.

If the game is over, the text "Game Over" should be drawn over the game board. You do not need to implement a new game,
for this exercise restarting the application is enough.
