All the best, mate! I try to do 3-4 jams a year. I need to find a way for them to be less stressful - probably do more planning and proof of concept up-front, since I usually end up with too many features and hit obstacles (I lost a day trying to get vfx to display in front of the canvas, though I'm not sure how I could have avoided that without experience). Building a portfolio is a good idea if you want to work for a studio, especially showing that you can generate ideas and functional games in a short time. Feel free to follow me on Twitter (@PixelShenanigan), I share a lot of Unity tips.
