No, technically not.
The dev still develops and post in his patron, just happens he has a pretty crappy health and perfectionism
I wish I could share your optimism in regards to the perfection bit. Don't get me wrong, I want the game to be as good as it can be and I want them to take their time, too. But... At this point I'd rather something than nothing.
Know what I mean? The game already looked miles better than most, both in graphical fidelity and in writing. To strive for something better is great but the cost has become apparent:
No actual update in a year and a half
No dev comment on Itch in almost a year
Latest Patreon post where they describe their fight with it (perfectionism)
There's a handful of games I follow that ended up on hold indefinitely or outright abandoned because the dev would chase perfection (Sylphine being a prime example). They've all followed this very same path and I'd hate for this to share the same fate.
