Here's a precis, since there isn't one, and some people have an issue with that.
MC lives with his mother and sister, it's the start of the holidays, I guess after high school, if we're using a US measure. MC is a bit of a moronic pervert (like 90% of MC's in these games) but hides it behind his even more moronic best friend (like 90% of these games). MC is looking for work for the summer, and gets a job as a photographers assistant. Things get interesting (in more than one way) from there. Morality and social norms appear to have pretty much skipped this universe, and noone seems to spend any time worrying about them, like he pervs on his 'housemates' right from the start, never has a thought about it being wrong or inapropriate, and when he is caught doing some pretty inapropriate things, he faces no repercussions.
I'll start with the cons, because they are obvious.
I don't see the point of it being sandbox. There is only one path, and it is linear with no real options. A couple of individual scenes can be viewed in a different order, but that is it. There are a few points where the MC has to sleep during the day to pass time for the next event, but only a few, so there isn't even much space to add additional routes or choices.
There are hints to direct you to the next task, but they are all in the dialogue and they aren't always clear. So there is no log you can go to if you lose your place. If you don't play the whole thing in one sitting, which is fairly easy to do now, but will obviously get harder as content is added, then I can easily see people coming back to it and being totally lost.
These were the problems I noticed. I only played it on 1.1 and I didn't experience any of the bugs or glitches people previously reported, so I assume they have been fixed.
The eh, kinda so so choices.
The game drops you right into the middle of the story, the MC and friends already know what the 'Red Room' is and therefore it is never explained so you have to work it out for yourself. Some people like that kind of thing, some don't. In case someone wants to go in totally fresh, I've explained it under the spolier tag.
The pros
It doesn't take itself too seriously, and the story moves along at a decent pace. There are a decent number of sex scenes for this early after release, though it is all pretty vanilla so far. The girls are nice for the most part.
The characters and the story is believable enough in the context of an incest porn game, though spotting the plot coming won't exactly tax you. Not least because the preview pics give half of it away, and the rest is just pretty obvious.
It's not exactly wholly original but it has a few moments, and by the same token its not a clone of something we've seen a million times before.
I debated 3 or 4 stars, and decided on 4 because I'm hopeful and cautiously optimistic, and I felt the 1 star review that was already up when I came to write this is needlessly harsh.
