As long as your game is on gd.games and itch.io, you're good.
Adding your gd.games URL makes it easier for us to check that both versions exist, but as long as your itch version got in before the deadline, and your gd.games version is up on the website, you're fine.
But please add the link to your gd.games version in your itch version game page description, so it'll be easier for us to find later. 👍
