Hello, I wanted to take part in the jam myself, but unfortunatly I don't have time for a full blown game. But I still want to take part and make music for soup likes in this jam. So, I guess the question is can I link my previous works with my discrod? Or is there a specific Discord server for this kind of thing?

Yeah, you can use this community board to post your work and reach out to others if you're interested in collaborating!
