Alpha 12 was ALREADY out, patreon only, until patreon gave it the boot for pretty blatant content violations.
since then it moved on to pixiv fanbox or something, apparently just-released patreon substitute, some weird japanese patreon clone, that only deals in yen.
So far only alpha 11 is available, NO WORD on alpha 12 free release or alpha 13.
last months update window (18th-25th) got missed
the dev is barely if ever online on its discord, and last post was
"huh what'd i miss
game
is def not getting abandoned don't worry guys"
on 28th of june after a missed update window.
Dev didn't read up on patreons (and most other patreon-like) content guidelines, got perma-banned as a result, apparently refuses to wisen up and export problematic content to standalone mods / player defined relationships, and rather moves to whole project over to a foreign, completely new payment processor.
Nice game, but if it will not get abandoned soon anyways, idiocy has doomed it to obscurity. I for my part don't expect another update anytime soon.
