An action platformer inspired by the Super Mario gameshttp://retux.nongnu.org/
ReTux (stylized as "reTux" in-game) is a libre 2-D platformer written
in Python and utilizing media from SuperTux.
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.
The main game contains 41 levels split into 5 worldmaps. Each level also
has a Tux doll which can be found for bonus points and 100% completion.
