I just checked the developer's Patreon page. News there is not much better with this posting:
Bouncing Back, Overcoming Setbacks New Apr 22, 2023
This repeats the absent developer situation now for far more than a year.
I, like many others, find this disappointing at the very least. It would be different if there had been more postings between April 2023 and now so we would know how the developer is doing if they are still around. As of now it seems unlikely.
