I'm also (somewhat) in the same predicament as violinistsMetronome. I wanted to contact you so I could get that 5 days after the jam to complete my entry, but I couldn't find your contact info; I don't have a tumblr account and don't know how to use Discord, so I can't use these.
Would it be okay if I were to submit an incomplete version of my entry before the deadline, then update it with a newer version post-jam?
