on march 3rd, he released build 0.1.6 on patreon, 3 versions ahead of what we have currently. either he's abandoned updates here or he's completely forgot about itch.
He posts a public update two weeks after the new one in patreon, and it's also posible that he just posts an earlier version... I'd just wait a couple of days to see if he posts 0.1.5 here before making assumptions.
