Itch has it’s own age limit of 13 or older for anyone using the site, and if you’re under 18 years old you require the permission of a parent/gaurdian.
As long as you’re above their minimum age requirement, you can join the jam, but you may not be able to claim any cash prizes yourself if you’re not old enough to have your own account.(It may have to go through your parent/guardian, or you can choose a charity to send it to instead.)
