I think the game is dead.
The dev's supporter site has not progressed since July 23, and the 0.1.6 has not been released for download on itch since then.
Honestly, I will say what I say about every case like this. Patreon is where you take money from people, so it should be the first place where you post updates, followed by storefronts like Itch or other places where you advertise the game. Even if it's just something to let people know what you are working on and that you are still alive.
If you don't post updates there, people will naturally assume there are no updates and the development is either dead or in limbo. Most will not bother to check Discord, assuming the updates there are not paywalled in the first place.
