Recently there have been a lot of reviews that are fighting each other. A wave of 1 star reviews for the recent updates and then comes in 5 star reviews that serve the purpose of combating the 1 star reviews. It's become a cycle of underrating and overhyping from what I can see.
I don't see it as either 1 or 5 star. It's definitely in the middle for me. I like this VN. I don't love it but I do like it quite a bit. It has a cast of pretty good and diverse characters with their own personalities and quirks and they all bounce off one another well in their interactions.
The dialogue, for the most part, feels real and the MC and his twin sister, the titular character, Haley, have what I believe to be the best brother/sister incest dynamic in an adult game so far. I don't think any other game, past or present match this. I've learned recently that Ptolemy is the writer and his previous game had one of the better brother/sister relationships in adult games, so he very much continues that stride here.
The story, for the most part, has been light-hearted and fun to be a part of. That said, Haley's Story never really hit any groundbreaking developments until recently. Before these last 2 recent updates, when you looked at Haley's Story, you would struggle to identify this story. There wasn't anything worth remembering. Again, until the last 2 updates, which is where the polarizing combative reviews are coming from. Now, Haley's Story is beginning to leave it's mark.
Things are revealed about Haley that leave a sour taste in people's mouths, some for good reason, some for fallacious reasons. I have no problem with the current development, as long as it is handled correctly. Right now, that's only about half the truth. The way this character arc came about was totally out of place and seemed to happen solely to cause drama for the sake of drama, which is bad. At the same time, Haley's current attitude towards this subject matter is handled very maturely.
At this point, it cancels out. The startup was done all wrong but the current development is being handled with the care that it needs. But this is where you must bring up the sudden shift in tone. The tone has drastically changed due to this reveal. You don't feel it through the dialogue. You feel it through the MC, who is very much feeling out of place due to the sudden bomb drop and it hangs all over this update (v0.60), which can be a problem considering the game before this has been rather tame and inviting. Now it's cold and distant, which wouldn't be an issue had it been handled with better care.
So for any future players, take the sudden tone shift into account before playing. That way you won't feel blindsided by the coming development.
All in all, this game is a solid experience with a few hiccups here and there. It has the potential to be a truly hard-hitting story but has the same potential to become a train wreck if certain developments are not handled properly.
I'll give this 3/5 but I'm leaning more towards 3.5/5 for the balls to delve into certain subject matters.
