Short Rest will always take “late” submissions as strict time limits are Not Cozy. So no worries on your cozy submission, it’ll be here when you’re ready.
I definitely appreciate that. How would the mechanics of it work? Is there a way to add a game to the jam page after it's ended, or would it be adopted into the group some other way? (I say because the stress of trying to get my wizard game done in time was, as you say, definitely not cozy.)
