There aren't exactly "rules" for our jam (it's all pretty relaxed). We're hoping most submissions would have been worked on at least a little during the jam period, but we'd rather more submissions than not. So, if there's some more work you can do on it during our jam window, that'd be rad; if it's done and you just want to submit it as is, that's better than not sharing it with our community at all, so sure.
