Not much to say , compiled out of the box and it is insanely fast if you
choose the hardest setting.  (Hardly the best game on os4 by now but hey
...)

Update: 2 Sep 2002:

Added a difficulty selector that lets you modify the speed of the game,
and notes this on the high score list. The game should not be quite as
insane as it was originally (or will be more so, should you so choose). I
also fixed a subtle timing bug that made the easier difficulties
unplayable.

Known issues:

There's no sound. Anyone with sound effect making utilities is welcome to
create shots, missiles, lasers, and explosion sounds and contribute them
to the cause. Background music for the levels, boss fights, text-scrolls,
and various subsidiary screens would also be appreciated (in MOD, S3M, XM,
or IT format, by choice). 

Dvorak keyboards don't seem to play properly with the game, though it
isn't clear whether this is a problem with SDL, my use of it, or with the
configuration on our Dvorak-users' system. I suspect I'm using the Unicode
conversion wrong. 

The game is fragile about where files are located. It would be nice to
make the game installable in some central location where everyone can run
it and load the libraries and data, and where the high scores might be
safely modified by everyone.

CHEAT:

If you're getting reamed by the alien hordes and just want to watch the game
go, type "rhubarb" at the main menu.
