just wanna know
i think there isn't a minimal age to join a jam, and if there is, the jam itself will say that (e.g., adult jams and jams with money prizes will specifically say they are for ppl over 18). And i already saw accounts of people in itch with less than 13 years sooo... as long as you can make the game, go in ig
The thread is old and incidentally OP should now be of legal age ;-)
But that's actually tos territory and not something of opinion. It's a legal problem. https://itch.freezing.top/docs/legal/terms#2-users-and-publishers
It's basically the same issue that's with opening a youtube channel. You just can't do that without parental consent as a minor, and under a certain age not even then.
There are game sites for younger developers.
