That was during the de-indexing of the majority of Adult Games. It seems like they've returned the games to their original state (as long as you enable the no payment methods options.) It should be able to be found normally now, but I'm not certain.

I started developing the game quite a long time ago, but unfortunately, progress has been extremely slow due to the busyness of life. So, I’ve decided to pause everything else for a while and focus fully on development.
My plan is to release a playable first version and try to generate at least enough income to continue working on the game consistently.
Hopefully, it’ll turn into something great in the end.
