Yes, or have a general thread for all the "games", it's IMO, more efficient to bring some more stuff to an already active community than to have an empty community. This kind of daily threads helps keeping the c/ active
I'm not sure if jerboa has an option to create a community. But you could also just make one by logging into lemm.ee (the website).
But as mentioned by another commenter, it might be better to do this in another community. Lemmy isn't big enough for very niche communities like this.
Thanks for sharing the game. Can't help regarding the community, but my wife has a collection of Wordle inspired games she does daily. I think she'll enjoy this!
