It's a bit of a dumb question, but are teams allowed? If so, where can I ask for one? Is here fine?

Hey there!

Yes, teaming up with other people is absolutely permitted and actually expected - you can ask around here, but we also have a game jam channel on the Preggopixel's Games Discord server. You will probably have most luck there!

A link to the server can be found on the Jam's main page - the bottom link under "Community Support"!

Hope this helps!
