How long is one playtime from the start until the end of 0.4? 5 hours?
I have a few different paths and deliberately read much more slowly than I normally do (conversation speed for someone not from New York/Boston or from the "Deep South" - somewhere in between
), while also taking in the visuals and letting animations play.
I probably spend a good three hours with each release because of this, maybe as many as four if I'm trying different things with it. This is a quality game with lots of good stuff going on visually, a few different route choices, and a nice amount of good dialogue, so it takes a little time to "do it right", at least as I define "right".
I've been playing my various games "in order" (amongst those currently updated, playing the one I played the longest time ago) instead of jumping on this release immediately like so many others, so still haven't done 0.4, but I probably had around 10 or so hours into it up through 0.3. I don't really time it, so it could be less than I think it is, but probably not by much.
Quick flippers just looking for the lewds can probably get through a release in an hour or so, faster if they allow the skipping of unread dialogue and only pause for the lewd parts.
