ReTux is a 100% libre software and 100% libre culture action platformer loosely inspired by the Mario games, utilizing the art assets from the SuperTux project. The name "ReTux" is a play on the words "redux" and "Tux". Although ReTux re-uses the art assets of SuperTux, no code from SuperTux is used in ReTux. The software portion of ReTux is entirely new, written in Python and based on the SGE Game Engine. ReTux also has several distinctions in its gameplay compared to both SuperTux and the Mario games.
