// A video game based on Homework 8
// User must click the moving figures.
// Each figure is worth 1 to 4 points based on the color of the figure.
// Player has 1 minute to score as many points as possible.

/**
<B> Directions:  </B>  <P>
    <HR>
    Click on the moving targets.  <P>
    Every one you hit eliminates the target and adds points to your 
         score.  <BR>
    Every one you miss adds two more targets to the game and you lose 
        points.  <BR>
    <HR>
    Eliminate all of the targets and you win!  <BR>
    Run out of room for more targets and you lose!.  <BR>
