I handful of people have asked me if it was possible to have multiple accounts edit the same game page. It’s now possible with the new game admins feature!
A game admin is someone who has access to a game in your account as if they had created it. They can edit the basic data, edit the appearance, they can view the game when it’s not published yet, and they can see all of the game’s analytics.
When a game admin is approved the game will show up in their My games page.
You can find a link to the Game admins page in the Edit game tabs. Just type in the username (or their itch.io subdomain name) in the field. Game admins need to approve access to your game. Send them the generated link to let them get access.
