Till Itch resolves the payment issues for adult games, they have delisted all nsfw games that accept payment. That's paid games and pay what you want games.
Being indexed does not change how followers see your devlogs.
If payment still works for your games, you could consider uploading a new free project as a demo version, like a shortened web version. Being indexed is good for getting new players, and having a web version can also help there.
Different people find different things appealing. For me your screenshots would have worked, as they show that the game is a bit more complex.
But I already was hooked before by the princess game, so I knew what quality to expect ;-)
The idea with the shortened web version would also mean you could have different cover images. Or think about exporting some of the minigames as a standalone side project to reach more casual players that like web games.
