Not gonna sugar coat it, the first 10 chapters or so are quite rough in terms of renders and animations, but it progressively gets better. I don't really understand the point of adding music as late as ch23, so consider this as an AVN without music I guess. Maybe they'll go back and add music for the earlier chapters before steam release...So is this worth playing? The renders don't look that great and it looks like music isn't a thing until chapter 23. That's a long trudge to get to all the way from ch 1.
That said, yes, it's worth playing it... it might be one of the more complex AVNs I've played in terms of relationship paths and options, and the story is quite solid too.
