I'm so excited for my VERY first game JAM!

I have no clue what to expect, but I'm sure it will be very stressful and fun. I'll be using Unity as engine, Photoshop for 2D assets, Blender for 3D assets and Ableton live lite 10 for the music (if I ever get to that point...).

Any GAME JAM VETERANS with tips for a slightly anxious first timer? I'd really love to be able to finish something!
