I was browsing throughout the old gain jam pages and found a great game, unfortunately, it appears that a great game I dug up, Plasma Belt, from the 2020 gain jam, has been discontinued, and playing through it, it was a great game, and to not get any continuation or update is kinda sad
I’m afraid asking for updates is against the rules (though this might somehow count as an exception, who knows). Regardless, unless you intend to make it yourself, I really don’t see who is going to do it for you.
there have been games that show updates outside of the jam, like a post-jam version
That’s entirely up to the creator of the game. If they want to continue the game, they will. If they don’t, then that’s it. They don’t.
