Like the title says. The intro mentions ideas we've been musing about but haven't gotten to. I've got one, but don't think I could finish it in only a month. But could I start on that, or are we looking for completed (and shorter) works?
This jam is just meant to motivate writers and other creatives to start/finish work on their Touhou stories, so you are allowed to submit a work-in-progress entry to the jam for progress gauge/feedback purposes.
