The guys over at the TwineGames subreddit
are launching what's hoped to be the first installment of a long serie of Twine Game Jams.
The theme is exploration
and we've got until the 14th to submit our entries.
It's a pretty good way to practice our writing and work on very specific parts of an existing project.
For example with the exploration theme, you can set up all the places/room where your story will happen, not focusing too much on gameplay elements.
Don't hesitate to share here the result of your hard work :-)
