Sorry if this is a FAQ, but I couldn't find a clear answer. I get submitted games need to be free, but is $0 or donate allowed? Or should I select the 'no payments' option? Thank you.
On top of the comment above, I believe the general rule for why a game jam project should be free is for people to be able to access it and judge it as part of the competition.
So “$0 or donate” should be a valid option (assuming the game jam rules say otherwise) because it lets everyone access the game without issues.
