TC Swordplay is a game where you block and lunge your sword against the
computer's sword.  A hit is made on the computer when you are able to
maneuver your sword past the computer's sword.  Also, a hit is made on
you when the computer's sword is able to pass your sword.  The trick is
to get past the computer's defenses and strike the computer before you
get hit.  A good strategy is to lunge your sword while changing direction
simultaneously.
