-I have been playing this one for quite a while now. However, you can make it
-substantially easier by slowing the game down. New in version 0.2, we have a
-constant GAMESPEED in config.h. New players may like to try it at 3/4 or even
-2/3 speed. It should probably be a command-line option, but I'm too lazy to
-fix that right now.
