Maybe it has something to do with the big winter sale going on and the system / admins are much busier than normal. That could very well be part of it.
I even made a dev log which I read was supposed to help to get your game showing up faster. But even my dev log itself doesn't show up in search. LOL
All I can think is maybe if we comment on each others games that might help us both out? Might trigger the system to wake up "oh hey there is some activity on these games"
Mine is here... worked my butt off on it be nice if it actually showed up. lol Anyway our games do not compete at all with each other so maybe a comment will be good all around.
Here is my game... https://garbenjamin.itch.io/garsdefensegame
And I just commented on yours and I didn't think of it until just now but I will also follow you to see if that helps to get you existing in the search.
