I think a major problem was the lack of a community platform. I assume that the in person jam had an entirely different feel. Online jams if they dont have an actual community place to really hang out makes you feel disconnected. I was lucky enough that I knew many people through attending local game dev meetups here in munich and other events, so I knew some names. I also am part of many game dev communities, so there was a sense of comradery. For the next jam I hope we actually get to make it an in person even with multiple locations instead or have an actual community hangout.
