Good afternoon, I recently uploaded my game Dawnfall ( https://zebual.itch.io/dawnfall ) and just saw that my game does not appear when I search it. Is there any issue with my game? What can I do to avoid this in the future. Thank you for your time.

But long story short, your game needs to go through a manual review before being indexed.

It's impossible to tell you how long it will take; it can range from a few hours to a couple of weeks, and there's nothing you can do to prevent it, as it's designed to prevent bad actors from uploading viruses or similar.
