I’ve noticed your indexed games have tags but “what is it like to taste” doesn’t. Maybe tags would help in your case? It’s a wild guess.
I’ve seen older games with regular high amounts of activity get deindexed after updating and my own game was deindexed while receiving a decent amount of activity too (And I updated it once).
Optimistic question: Was that at the same time of the mass deindexing or was it after projects starting being reindexed?
I don’t know any deindexed dev who has successfully contacted support about this issue.
Yeah, I’m the only one I can think of, and I’m not primarily a game developer.
