penguin-command (Missile Command clone)

This is a clone of the classic "Missile Command" Game, but it has better
graphics and music. The gameplay has only been slightly modified. Penguin
Command is licensed under the GPL.

By default, the game runs fullscreen unless you pass it the -w option. If
you want to patch the code so the game starts in a window by default,
set WINDOWED=yes in the SlackBuild script's environment. This only
changes the default, it will still be possible to use the -f option to
get fullscreen mode, or press Alt-Enter to toggle fullscreen mode.
