If people just drop links without engaging with the community our Discord and Itch community will just become a posting board. We are having a large influx of unrelated links this year. You joined our Discord channel and posted your video link on a tenuously related subject in an unrelated channel within 20 minutes of joining.
If you have content specifically related to and engaging with GBJam we'll be pleased to see it. A popular format is a review of the games which are released at the end of the jam.
