I created my first game , Roll The Ball , and uploaded it on Itch.io here https://joe-brar.itch.io/roll-the-ball . But it is not appearing when I search for it on itch.io . Can someone tell me what's the problem . Should I check or uncheck the box saying "Unlisted in search & browse" ? Also my game is currently in a game jam , if that has any effect . Thanks !

It should be unchecked. And being in a jam should have no effect. Presumably you did check the Public radio button?

I don't see any issues on our end, looks like the game is indexed to me. Perhaps you changed a publish setting?
