Hey! Holly cow that's great! I don't want to say there is a limit on size, but curious as to how many people we are talking about! Something to keep in mind is a good number of us are just going to be working solo, like myself and Fwiller. So if the group is like 3 people, I feel that's acceptable, but if you are more than that, you might be a little big for our small jam. Idea after all is just an excuse for practice and fun, we aren't all striving to make anything too huge or polished, but if able to, all the more power to ya!
As for everyone joining, I think it would be fun, get to chat with people, artists of one team helping another, I will be opening ranking up but it's not like there is a cash prize or anything - we be a chill jam with bad puns at the ready, and not professional at all.
Further rules and the link to the discord will be posted in my final post which I am working on and will be posting before the jam starts so keep an eye out for that.
If you have any other questions, just ask or wait for the final post to be made, glad to have you and your group with us and happy that our dinky antics can be your first jam!
