public class DemoGame
extends JFrame
implements Runnable, KeyListener

The main class for the Demo mode of FROG. DemoGame features a four-player game in which cows are abducted by UFOs and it is up to the players to save the cows from their otherworldly fate. Players perform the gestures that appear on the UFOs coming for the cows. Successfully performed gestures will destroy a UFO of that type, awarding points to the killing player, and buying a little more time before the next UFO swoops in.

DemoGame is responsible for setting up all the internals of the game such as the sounds and images that will be used. After starting the DemoController which manages input and output, the DemoGame will continue to maintain a stable FPS until the game has been exited by pressing the ESC key.
