SPRITE GAME
-----------
Here you will start the beginning of a game that you will be able to update as we
learn more in upcoming chapters. Below are the criteria/constraints that you
need to include:

1.) Find some new sprite images.
2.) Move the player sprite with arrow keys rather than the mouse. Don't let it move off the screen.
3.) Move the other sprites in some way like moving down the screen and then re-spawning above the window.
4.) Use sounds when a sprite is killed or the player hits the sidewall.
5.) See if you can reset the game after 30 seconds. Remember the on_update() method runs every 1/60th of a second.
6.) Try some other creative ideas to make your game awesome. Perhaps collecting good sprites while avoiding bad sprites.
