I don't know what the criteria are. Please focus on doing your own promotion instead of relying on the site.

Would you approve a refreshment of "recent" for a game that has been launched a week ago?

Your game is still is on recent on page 9 for adult games. And on page 2 for furry games. Page 2! For all intents and purposes in regard to your target audience you are on top of recent. All the people that regularly browse recent for such games will see your game cover.

My impression is, that a realistic expectancy is 2-4 months. You also have this to consider: there are a lot of games and a lot of devs releasing "major" updates. So it stands to reason that there are more major updates than there are new games. Would you, as a user, expect the sorting of the platform that shows you the most recent games to display mostly old games or mostly new games on top?

They should really add a sorting with recently updated or whatever. It is ambigous what recent means. The url calls it newest and not recently updated. So I guess the intention once was to have a sorting by publishing date. But that was watered down with the inclusion of a bump due to a major update.
