make sure your quest submission is only one page -- per official rules everything past the first page will be ignored for judgement, so if your submission includes a "cover" page it'll actually be disqualified since the first page isn't a quest.
I'd be less of a stickler on this but the jam has started and I've already advised one participant when they asked if they could have a cover, so please mind the rule so it doesn't bite you!
(You can still upload a version of your quest to the itch page you're using, just make sure to submit a quest that has all applicable quest map and noyes on its FIRST page only!)
Thanks!
