Hello!
I'm glad to introduce my first game, animal rights themed "Yourik the Intergalactic Rabbit" (yourik.sourceforge.net). It is a simple arcade with a non-linear plot (there are two different endings) and large bosses.
Yes I know that Qt is not a preffered toolkit for games, but at the time of development I just wanted to make a game quickly, so I've used the familiar tools (C++/Qt, Inkscape, GIMP).
The code, graphics, music and sounds are made by myself and I've put them to public domain. There are source code and Windows build on the site. The source can be compiled and installed as root with commands:
qmake
make
make install
Now I'm working on the game "Yourik 2", with the same hero, but with different engine (C++/SDL are used) and another genre.
