I have to defend the dev in this case: He uses a post he made on the 16th on Patreon which he updates with a new progress screenshot each time and that's why it says Nov 16th.wtf it's dated Nov 16 . Someone just forgot see the date or correct it lol. ( I am assuming it's already finished he is just waiting it out)
No idea why he doesn't just put it on top of his Patreon about page but it is what it is.
