Just got done playing for first time (took Father route).
This leaves much to be desired as a porn game.
...And does a relatively good job as a dramatic VN with nudity/sex scenes. Personally, the Father's route was some of the best writing I've seen among the crop of "western" dev-made adult games I've ever played. It could be better (need some more insight into how the Father and Wife's relationship deteriorated-- time + vague hints that the father was a workaholic don't cut it ,especially since it's revealed he works from home), but I like it.
But there is the elephant in the room. It seems like the compromise for not deteriorating the writing is to have the secret imagery, which is fine, I think, but also leaves me wanting more content there. This is especially because the models used are nice all-around and, well, I want to see them nude//fucked.
Keep it up.
