Hey, my game is the one in question here. I wasn't aware there was a whole issue of putting together assets and storyboarding before the weekend of. This would be my first jam. Am I still ok to enter?
Yeah! You can enter, there's just a button which you click to show you've made assets before the jam time started.
Traditionally in jams you complete them (or don't finish completing them sometimes, as I've done in the past) in the jam time. Some jams last a week, some a month, many a weekend.
I personally think storyboarding is fine, like taking code from games you've made in the past, but making assets beforehand should be marked.
