Hello, in fact, the start date of the jam is 1 Dec 2023. I will also disclose three selected themes on that day. Every entrant will be required to choose one of these three selected themes to make entry. Please don't forget to pick one of the three selected themes for developing the entry on 1 Dec 2023. Good luck!

Hi!
"I had previously assumed that all 3 future-selected themes need to be included in the game entry instead of just any 1 of the 3 selected themes." <--- Yes, only '1 of the 3 selected themes' is required for each entry.
"I suppose a participant could still try to include all 3 themes together." <--- Yes, this game is an example: https://itch.io/jam/jam-for-all-basic-dialects-3/rate/1685296
Good luck.
