We've already added the screenshot; you can see it on the game's page & in the collection of screenshots for the games in the jam.
First of all, no, I can't see it on the game page. And second, I meant adding it right here, to the release announcement, which is what the rules ask for, There's no rule for having a screenshot on the game page.
Thank you for clarifying! We've added the screenshot to this page!
