Glad you liked it. As for ep4, Oooff. I slipped the Patreon deadline for it so it's coming out a week/week and a half into October sometime. Moving forward after that, I've extended dev time from 30 days to 45 days per episode. Can't sustain a 30 day dev cycle without major compromises.
As always, the public release will lag an episode behind the Patreon release, so ep4 will get a public release when ep5 is out for Patrons.
