Wondrous news: our Discord server is neither dead nor fighting within itself!
Jokes aside, hosting in too many different spaces would be a bit difficult to manage and in complete honesty there just aren't many other platforms that enough people would be interested in aside from Discord to warrant hosting a space in them.
As a note, participation in the Discord server isn't required to participate in the jam! You're free to engage with the community here in the community tab, and if you're looking for a team we have other avenues such as the team finder or the itch community tab!
