Hi! Sorry for the late reply, we've mostly been focused on the Discord in the post-jam period. We had announced there that we had a week-long grace period for people who had started but run short on time or had trouble submitting for whatever reason. The deadline is September 7th at 00:00 CEST (UTC+2). You can follow the directions in the Discord or, if you aren't on Discord, you can post here again and we'll send you a late submission link.
Whether you can or can't submit now, you're welcome to join us for next year's TRJ in mid-June, continuing with the same idea or a new one!
