Last Patreon post was dated 14th August and was a poll for 0.50 and a progress post for 0.40 all in one, within that post he said that 0.40 will be released to $10+ patrons that weekend. There is a current public post on the 3rd August in which he does describe that he works full time as well as house stuff:
'I do work a full-time job as well as having to, you know, do house stuff. I aim to spend 2 hours each evening and 10-20 hours over the weekend working on this. Occasionally I will vanish for a day or two when I feel like I am going to burn out. Honestly, the support has been amazing and has encouraged me to put this amount of time in. So thank you, everyone.'
That said me messages and comments are (as of writing) unanswered.
It would also appear that others are having the same experience.
Now I'm still a $20 patron as of the moment since I tend to be the most hopeful of people, I don't want to come off as harsh but whatever it may be: Conscription, Jury Service, Illness, Death in the family etc etc. All it takes is a quick 5 minute post to explain. Being available to the community or even at a minimum updating a progress post or just commenting on patreon, subscribestar or F95 is, in my opinion, vital to a dev.
So at the moment I'm not condemning nor condoning until we get a report or it's been a few months without update.
