Hmm not sure how this community thing works. Apparently the initial node you try to post in a community is sent as a normal note, and it's just added to a community depending if the poster wants to and a moderator approves (like this note).

Would've been great if I can post in a community and it stays in a community / not appear on my normal timeline/profile.

Anyway, looking forward to checking out this game when it gets released. Looks good https://www.youtube.com/watch?v=JbKjqVtthPk
