I'm experiencing the same issue with my game — it’s been published for 11 days now, and everything is set to public, but it still doesn’t show up in search results.
Here’s my game: https://dnamol.itch.io/holidays-saga
Published: 11 days ago.
So you’re definitely not alone — maybe it's a bug or some hidden delay from itch.io’s side. Let’s hope someone from the community or staff can help us figure it out.
Good luck to both of us!
