Hi! The jam is over. From what I understand, the best place to reach to connect with the community of blind gamers (and blind gamedevs) is on the Audio Games forum: https://forum.audiogames.net/
I also have a Discord server with a channel for the jam; while archived, it contains a lot of useful information in the chats (and pinned tweets). If you’re interested, the server link is: https://discord.gg/frKXYtG
