Not sure what any of you are expecting, an essay? The dev is probably already burned out, and releasing the paid version accidentally may have pushed them over the edge - assuming it was indeed an accident. If you've followed them for a long time, they've basically been working on H-games non-stop since what, 2013?
I hope there'll be game-over scenes for the bosses like in their previous games - though I could easily forgive the absence, when each enemy and their animations is probably already a ton more work.
