Some final notes/context:
The jam was created on a whim, following a discussion about parsers created in French throughout the years, which were mainly during the annual competition. The jam was meant to have a no-pressure space for people to make parsers, or even just testing a parser engine for fun. All throughout a whole summer.
While there were not many participations for this jam, there were quite a bit of discussion during the event in the French Discord. Multiple members having ideas and starts of proof of concepts, even if they were not submitted (maybe one day?).
Even with the three entries, there were quite some diversity. Each entry used a different engine, including the French-made Donjon.FI, as well as settings (fantasy, slice-of-life), or how they looked at puzzles.
So I’m pretty happy about it 
And I hope we’ll have even more fun next year!
