For our team it was getting used to same platform(with version controls and game engine) as Our artist was new to unity and animations and programmer has little knowledge about GitHub. We tackled it by communicating and sharing the knowledge :)
The whole game making experience was very smooth since we had a clear idea what is our final goal and everyone in the team pushed themself to achieve it.
Few takeaways: Time & Team Management, Contributed on other things apart form the work I was assigned and at last it is the people I met and worked during this Jam :)
