Racing Game
The purpose of this racing game is to allow you to make 
a game for two people to play at the keyboard.  Make sure that
you are gentle with the keyboard!
Open the project.  You can see that the directions are 
written on the screen.  For the bat, you set its direction
by pressing an arrow key, and you make it move in that 
direction by pressing the p key.  Likewise, for the horse,
you set its direction by pressing a, w, s, or d, and 
you make it move in that direction by pressing r.
Your job is to actually write the scripts that control the 
bat and the horse.  There are some scripts that have already
been written, but we have hidden them because you have not
yet learned those concepts.  For example, when an animal 
crosses the finish line, it says "Yay!"
You need to focus on making it point the proper direction
and move when the appropriate keys are pressed.  One has 
been done for you.  Click on the horse in the sprite list 
and then look at the script.  When the user presses the 'a'
key, the horse points to the left.
Have fun!
