I've recently been working on a game. I know how to make a title, but have no idea how to make the description on it.
Is it as simple as that, or is it some other way?
If you mean after you check it in, there is a description field for that (where you can type it in. You'll find it under "Edit this Listing" on your game's page. Otherwise, I'm not sure how to get a description into a game and how that would even look...
