How long is it? I see that it's version 0.9.3, is the full game available?
It's feature complete and content complete. One of these upcoming versions will be 1.0 but it'll be making menus and stuff nicer, I wouldn't worry about it. As for play time, I don't know, I never timed it, but I'd say around an hour is probably right? Less if you skip forward a lot and read quick. More of a "Visual Novella" than a novel.
