Here is a game I made in a single hour for OneHourGameJam the theme, and thus title is: Chess
Working on a game in an hour is a great way to learn the weaknesses about your development pipeline, be it in coding, art or audio. The result is almost always a project that will get thrown away, seriously it took 60 minutes to make, but the experience is certain to teach you something and sharpen game development skills.
The game has nothing to do with the game of chess, or theme. The plan was to have the blue squares become pawns and then have other pieces behind them, but 60 minutes was not enough time.
