I am joining this game jam called Devtober and they gave us a tip that we should post an update about our game everyday. And I think I will use itch’s devlog system in this jam. Do the game needs to be in published so that people can see my devlog?

In order for a devlog to be visible the corresponding page it is attached to must also be published.

Feel free to create a placeholder page for your game if you’re not ready to upload anything yet.
