Pingus is a free computer game inspired by Lemmings and created by Ingo Ruhnke. It features penguins instead of lemmings. It has been reviewed favorably by CNN.com, about.com, Unix Review, and other publications.
Work on the game began in 1998. This game is the first Game of the Month by The Linux Game Tome, which has revamped such games as SuperTux, Super TuxKart, and Lincity. The first post-GotM version 0.6 was released in 2003 for Linux featuring new levels and a level editor.
Pingus has only 22 tutorial levels accessible from the GUI, all with a winter theme. However there are many more levels included with the game not accessible from its GUI, some with entirely different graphics. To play a certain level the location of the filename has to be given as commandline parameter. Example:
A linux shell script that allows to choose from all installed levels can be found.
