Sweet, thanks for the speedy reply!
all roads lead back to noob-ness ;)
Some jams have very limited development time constraints (I'm thinking specifically of Ectocomp and the 4-hour-creation-time Petite Mort category), so updates aren't allowed after the jam has ended to showcase those efforts. Every jam has its own approach and rules, so I figured it'd be safer to check before getting too deep into planning, haha.
