The theme for Pyweek #10 was "Wibbly-wobbly", so we decided to make a game in which, in humanity's utopian future, the ultimate form of sporting entertainment consists of racing miniaturised spaceships through the intestines of people from the past - in this case, the various Presidents of the USA. Along with procedurally-generated digestive tracts and illuminating Presidential trivia, Intestinvaders sports three different game modes and an online "best times" system which allows you to watch or race against replays of other players' best attempts at the same race.
Intestinvaders 1.0.4 source distribution
There's no Windows package (at least for the moment) due to incompatibilities between Squirtle and py2exe, but assuming you have Python and the appropriate libraries installed the source distribution should run fine.
