It looks like the old topic on ReTux has expired, so I'm creating a new one.
:)
ReTux is a new platformer I've been working on, based on the graphics and
other media of SuperTux. Website is here:
http://retux.nongnu.org
This is a commercial libre game. Originally I tried to fund it on IndieGoGo,
but that campaign only turned up a couple hundred dollars, so copies of the
game are going to be sold when it is finished. In the meantime, ReTux can be
pre-ordered, and if you do so, you can get a copy of the current alpha
version right now. More details on that can be found on the website, in the
Downloads page.
Most recently, ReTux 0.4 has been released. The news announcement for that is
here:

This will probably be the last alpha release, because there are only four
levels to go (possibly five, if I make a special bonus level).
