I seem to have the same problem with a game I published a little over 1 hour ago. I don't know if games for sale just take longer to show up on the site than free HTML5 games (I made a simple html5 Christmas platformer last week and it appeared in just a few minutes) or if someone actually does need to buy it first?
It seems kind of strange if someone would need to buy it before it actually shows up. Kind of backwards. LOL
