This game is doubly Pythonic -- it uses PyGame, and it's based on a Monty Python movie.
It was originally an entry in the Pygame.draw challenge (http://media.pyweek.org/static/pygame.draw-0606.html). I've put a slightly enhanced and bugfixed version on my web page:
It requires Python 2.3 or later and PyGame with SDL_image and SDL_ttf support. That's all!
Comments, suggestions and amusing gameplay anecdotes are welcome.
