I'd like to show our project Smack! -- a 2D fighting game of chibi FOSS mascots. Intended to be a simple tech demo of our main project KonsolScript -- a supposedly easy-to-learn scripting language for aspiring game programmers. Both projects are Free and Open Source, btw.
Obviously, Inkscape was used to create the game sprites, which are available both in OpenGameArt.org and our SVN repo.

Late November, I ported our then latest copy to HTML5.
