Hey there, this is admittedly my first jam and I dont really know the ropes, but what now? Will there be some kind of discussion or celebration about the submitted games?
This was an unranked jam (pretty typical for TTRPG-related jams in my experience), so there isn't much of a post-jam process compared to something like the Ludum Dare. Instead, the submissions page basically acts as a catalog for people who want to find NASA image–inspired adventures in the future. If there's an adventure you wanna talk about, I'd say comment on that project's page directly; that way the adventure's author will see it.
We had a ton of fun participating and were impressed with the number and quality of submissions. One of us wrote up a lil post-mortem about the process--we invite you to give it a read!
