Here's my game, Yukon Escape! It's a side-scroller (or vertical scroller) game where the objective is to dodge obstacles. There are also the occasional threats such as earthquakes, debris, and forest areas that make the game more challenging.
I made it using the pygame library for Python in about 7 days. The development process was expedited in large part thanks to the codebase I have already built for my other game, Star Fighter.
