You do not know how lucky you are that this is the first game jam you joined. The community is amazing. Wheareas the first one I joined was made by someone looking to get subscribers for their youtube, half of the discord was bots that pinged whenever they said something on social media, and they did not play the games properly at all so when I submitted a full game with a long storyline that I worked on for a month it came last where all the other games were prototypes.
(ok, rant over)
