That's a shame. Are there any plans of adding it in in the future? Also, is there a way to go to city center?
Can't speak for the dev itself. However I think i can speak for myself and many more observers whom for many years now lost the "hope" for anything new being added to the game. That's because dev of this game mostly focuses on: layered clothing system, making changes every 6 months to it (heavy changes), body part expansion like breasts, hu-cow fetish and couple more...
"Fans" are still waiting - idk? over a year or two now? - for actual pregnancy of the Kira. Game files are already there, but dev for unknown reasons - just doesn't make it happen.
And there is also the overall mistrust situation that older players "accuse" the dev for milking his patreons, while they say he feeding them with minimalistic updates. Pretty sure also i have read over the years, here on the forum about that dev just do it for this game not to be tagged as "Abandoned" (technically still working on it, and just in time - delivering higher alphabetical letter to the game version).
I don't care about all those dramas, doesn't bother me if they are true or not - just to be fair with you. All i care is to be able to play the game.
