Ey Fuzzy,
I revised the Jam details and I couldn't find any restrictions on multiple jam submissions. I also didn't find a time limit for creating the game (submissions opened on the 1st of June but the jam was announced before that). In case you are interested on it, the game was made in 14 days.
Just trying to create things for the community to enjoy😊 (also, I believe anything with interactive can be considered a game if it involves the player properly, but we can disagree on that). If there is a problem with my submission I don't have a problem with taking it down.
