A simple blocks game made with python and pygame. Licensed under GPLv3. Used python 2.6.4 and pygame 1.9.1 for development. Tested on Linux and Win XP.
Update 2013: I'm sorry that the development for this game stopped. I tried to render everything with OpenGL and as expected, found myself in the middle of a multitude of problems relating to it. The blocks look a lot cooler in 3d though, so I hope I'll manage to resume studying what went wrong and eventually fix it. If I had a Windows machine...
