I made a game for this jam, but I never actually joined and now I can't join or submit. My mistake, but I would still like to submit my game, if possible. Thanks.

you need to join the discord

What then? I did join and messaged the host there, but is there something else I can / should do?

Thank you for your reply, btw!

Nevermind, I found the late submission channel just now. I assume I would post it there just like anyone else, even if I didn't join to begin with. (I am very unfamiliar with Discord and have a hard time navigating it)

Thank you again!
