So, HTML5 browser-only games won't show up, then? Hmm, I see... didn't know that...
UPDATE: this is not a duplicate reply. My first reply was addressed to the wrong participant. I deleted that one before posting this reply.
Only if your game has a minimum price. In that case it will have to be seen by an admin, which only happens once a day. Otherwise no. It's still possible that a given search doesn't return your game, or at least not in the first few pages of results, making it look like it's not indexed when it is. Don't panic!
