Pingus has started at the end of 1998 with the simple goal to create a Free (as in freedom, not as in free beer) Lemmings(tm) clone. In the years it has grown than quite a bit over the original goal and become something more than just a clone, we have original artwork, a built-in level editor, new actions, multiplayer and a few other features.
