+Description: Retro platform shooter inspired by Duke Nukem.
+ Dave Gnukem is a retro-style 2D scrolling platform shooter similar to,
+ and inspired by, Duke Nukem 1 (~1991).  The original Duke Nukem 1 had
+ 16-color EGA 320x200 graphics; the aim here is 'similar but different'
+ gameplay and 'look and feel'. It is kind of a parody of the original.
+ Please note it is not a 'clone', and not a 're-make'.
