That's really great advice. I got really worked up trying to do both Short Rest and March of the Wizards after coming off sad mechs and I didn't realize that it was obviously too much until too late.
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.)
