Last info was in january (patreon) so are you sure? This game has potentical cause most itch adult games are just stupid slideshow games. I also like Elf Ravager but there the dev has stopped working on it for the reason i already mentioned.
a good one is MouseTrap that said i get what your saying, the thing is with Itch almost all the games are made by Solo dev's or very small teams funded almost exclusively by the players, this game is no different it is also chapter based and the dev wants to only release major updates so everything is just taking time. a good rule of thumb for me is to check a roadmap or recent dev logs to see the expected time for the next update, if a month passes after the expected date i assume its been abandoned.
(Update) i just checked the socials linked above, the last update was in march it looks like (i didnt check discord)
(Update again) after checking discord it looks like the dev team fell apart
