Work on the game began in
1998. Version 0.6 was released in 2003 for
Linux, and featured new levels along with a level editor. On February 11, 2006 the game began being
ported from
ClanLib to
Simple DirectMedia Layer (SDL). On August 27, 2007, version 0.7.0 (the first version to use SDL) was released. In addition to
Windows and Linux, the switch to SDL enabled Pingus to be easily built on other platforms, including
Apple's
OS X. On September 23, 2007 version 0.7.1 was released with a new level editor. On October 31, 2007, version 0.7.2 was released with a set of
Halloween-themed levels. There is a Windows 0.7.6 and an Intel OS X binary of 0.7.2 available from the Pingus website. There is a
PPC OS X binary of version 0.7.0, while version 0.7.3 contains minor bug fixes that allow the game to work better with the
GNU Compiler Collection. The latest version, 0.7.6, adds additional
Christmas and Halloween-themed level sets. In July 2008, the game was
relicensed from the
GPL-2.0-or-later to the
GPL-3.0-or-later. == Reception ==
