Pingus is a free Lemmings-like puzzle game under development since 1998 and currently has 77 playable levels.
Pingus has grown to become more than just a clone. It features original artwork, a built-in level editor, new actions, multiplayer, and more.
While Pingus is based on the idea of Lemmings, it, however, doesn't try to be an exact clone; it has included a few ideas of its own, like the world map or secret levels, which might be familiar from games the Super Mario World and other Nintendo games. It also has a few new actions, like the jumper, which weren't presented in the original game.
