I'm kinda disappointed to see it's not out yet. Especially after it was stated by the devs following Ch 4's release, there wouldn't be big gaps between the chapters. Almost a year after Ch 4, still no Ch 5. I get that these things aren't quick or easy, but a year is a big gap.
3 months is the going rate of most other devs.
Also, it was stated that there would be more frequent status updates, that wouldn't be locked behind a paywall on Patreon. To my knowledge, that hasn't happened either.
And then there's Polarity, which as far as I can tell has been dropped entirely. Prove me wrong.
