I won't be joining the jam myself, but seeing that a lot of you are new to game jams, I will give you the little advice I learned over many failed game jams. The one thing I will recommend is to always make something that is simple and accomplish able but you can still learn from the experience. Failing to meet the time limits on a game jam isn't the end of the world, because you can always try next time. Always make sure to be on task, and you may finish your game during the time period of the game jam. But over all things, remember to have fun! I am not trying to sound like some corny camp leader.
