Lemmis

This game is called 'Lemmis' because it is a Lemmings-clone, it is made using OpenGL

There are ten different maps, sounds, Windows-dialogs, background-music and many other features...

At the moment there are two different versions of the game, one with, and one without music. The music is a feature that you do not need, if you have a slow internet-connection. It is however recommended that you try the soundtracked version since the music adds to the games' atmosphere.
