Also, you don’t fly to the tippity top of the recent category when you get a bump.
But that's literally what is happening when you get a bump. The time stamp for sorting in recent gets an update. And that is why this is coveted by many developers and why developers are very concerned about not being indexed right after publishing. This 5 minute exposure is all the marketing they have. Occasionally some people abuse this system, and I have seen one of those getting permanently delisted because of that.
Recent is sorted by date of publishing or last approved major devlog. I do not know if they use the time stamp of the update or the time stamp of the approval time or whatever.

One game is on page 2 of this popular sorting https://itch.io/games/tag-female-protagonist . That is 10000 games and includes the non adult games.
