Will there be more Scratch jams in the future with different topics?

We could, but I'm not sure how we could get enough participants. This time we advertised a lot in Scratch, Linda is even in the Scratch Team and announced it on her profile, in the forum and on the Scratch wiki. Still, we will get probably at most 15 submissions, I would love to see 50+.

On the other hand, for Scratchers that like to make games, there is always the possibility to join any of the other jams wich are open for any platform. For example, I submitted Scratch games to the 2 color jam, the Browser Game Jam, for Ludum Dare, for the Mini Ludum Dare 74 and for the Klagenfurt game jam. In short, if you want to make a Scratch game, there will be always a Game Jam nearby where you can submit to. See https://itch.io/jams for a list of ongoing and upcoming Game jams. I see the Scratch Jam mainly as a starting point for Scratchers to get familiar with publishing games online and with using itch.io's interface. In the future, I hope to see a lot more Scratch games around!
