Should the repo contain the full game, not only the code but the models / sprites / audio files etc? If yes, what if I use third party assets (I suppose it's not prohibited)? If I were to join the jam, I would use audio assets.
Ideally you'd share as much as you're able to. If you're using 3rd party assets that you're not permitted to distribute, don't include them. Please consider adding some placeholders in the repo, and a note in the README.
