True; time constraints meant that I cut that, the platforms(?) between 
you and the aliens, the random bonus alien at the top of the screen, and 
a high scores table (at least). Have to leave something for the second 
edition ;-)

I am quite unashamed in using uppercase variable names, particularly for 
default values, but I acknowledge that there are strong views for and 
against. I also find that lowercase variable names can get a bit "lost" 
in shell scripts, where everything else is lower case too. Having said 
that, C code tends to have all lowercase and gets away with it, while 
Java tendsToInsertCapsLikeThis, which I find veryIrritatingIndeed.
