Welp, apparently Nomo's in ill health, has been keeping it secret, and there's just no update release plans now. From their Discord and Patreon:
Hey everyone.
We're still working on KoD and have a lot of plans for the characters and story. Unfortunately Nomo has had some personal issues recently and has needed an ambulance a few times in the past few months, but is generally very private and doesn't like to go into stuff too much.
Due to that, we don't currently have an estimation of when we'll release the next bit, but rest assured it's being worked on. If you've supported in any of the months since we had the initial estimation you will have access to the update as soon as it's ready.
We sincerely apologize and hope for your understanding.
