Let me clarify that I don't work for the staff, so what I'm about to say is just a guess.

I see on your page that you submitted your game to several game jams. It's a bit unusual for the same game to meet the requirements of 5 different jams at the same time.

Could it be that you submitted your game to a jam without fully complying with its rules? I'm asking because if that's the case, it's possible that one of those jams reported you as spam, and that's why your game isn't being indexed.
