RE: Window command

I like Wendy's solution. I am more impressed with solutions that are easily
understood by students than the "most elegant" solutions.

Another solution might be to place a little border all around the edge of
your project area like a little picture frame and program this color so that
whenever a turtle passes over it, the turtle becomes hidden.  (Just give the
color the instruction:  HT)  If the turtle is drawing, it cannot respond to
color.  But if its pen is up, this will work.  The turtle will appear to
leave the window.

I'm not familiar with the game so I don't know if you need the turtle to
reappear or not.  If you tell us more about the game maybe we can help with
a better "quick fix."
