Some games are indexed immediately. Some take weeks (or months).
We’re expected to wait a couple of weeks before emailing the Itch.io about indexing. They’re chronically backlogged with requests. Multiple emails in one day for the same low-priority issue (compared to spam attacks, malware reports, life-and-death payouts) on the same day as the project was published likely won’t endear them to your concerns.
While you wait, you might want to reconsider the pictures of your latest game. In my personal opinion, they aren’t making your game look publishing-ready.
