Hi, I had a question regarding the rules on teams with people you don't normally work with. I was hoping to do this jam with one of my friends where he would be doing the sound and music, and I will be doing the rest. We've only worked together on a game once before this very recently and I was wondering if that is okay.

I have the exactly same case, hope we get  an answer for this.

This is ok :) this rule is more to avoid teams who work together on commercial projects
