Here is my attempt at making a game in the little time I had! I'm happy that it (mostly) works, although there are certainly more features I would have liked to add.

As it stands, it is a 2 player game. Player 1 plays on the left hand side and uses WASD and left-shift keys; player 2 is on the right hand side and uses cursor keys and comma. Both players have to try to run up a skyscraper that keeps growing out of the ground. You can also shoot bricks out of your opponent's skyscrapers to hinder their progress. First to the cup in the middle is the winner. 

The game is about 500 lines long, has hardly any graphics, and doesn't use any library except pygame. More info and code over here. Please enjoy!
