I also have school during the jam week, physical as well. However, I participated in the BTP Game Jam #3 a couple weeks ago - it was a blast - so I'm craving game-dev right now! That's why I'm not gonna let som schooling stop me. I'll aim small, smaller than usual, and I'm thinking of forming a team so that I don't have to spend lots of time on the non-programming-related bits.
