I've taken out the ability to add player names, since it wasn't key to the game, and you generally won't have access to a keyboard when playing. I've also enlarged the quit dialog and changed the end of game input to just wait for a screen tap to start another game.
Daniel did HEAVY keyboard usage in this game, but I found that only a few features were really needed to play. I've also hacked out his fonts and instead used the default PyGame fonts in order to save room.
I also added a startup splash window so that launching using d-bus would work properly.
TIP: When you are done playing, hit the hardware escape key.
All in all, it's a good implementation of Connect Four. Enjoy! Licensed under GPL V2 - see license.txt in /usr/lib/connectfour
