Hello,
Sorry but your itch.io Jam's name it's "Showcase Jam 2020", only the Twitter name is "TTRPG".
You made a little mistake, I think, so most of the TTRPG games must come from the Twitter. And You are not clearly visible as a TTRPG Jam on the calendar, it's sad for you.
I almost made the mistake twice so it's not really clear, and I always read the rules :).
Whatever it's cool to have a TTRPG Jam even if you can't count on me to do a Narrative thing in English language :).
