Yup, this update is superb, IMO the best one yet. Felicia and Mina fans will be delighted and since they're the best girls (along with Hana) everyone will be delighted by default. I don't want to spoil your fun so I'll only say that devs have set new standards when it comes to making VN appealing. There are tons of little things that make this update (and game overall) above all others, you even have a passage of time taken into account and depending on the order of things we do we might get slightly different scenes or from slightly different POV. This adds to replayability and makes the game much more immersive.
Devs also remember things and choices we've made much earlier in the game and now we either have to face the consequences of our actions or we're presented with unique opportunities that wouldn't be available unless we've made a certain choice. All in all I'm amazed how much they can squeeze out of VNs (and GIL out of Honey Select, his images are better than 99% of DAZ renders), at times I forget it's an erotic visual novel, instead I see some RPG elements and an illusion of open world.
I also forgot how big PC updates are when compared to other erotic games we're getting. Seriously, it takes a significant amount of time to finish this update and even then you have to replay it a couple of times to see all the scenes (and it's not tedious since we're getting a totally different experience and there is no grind here).
If anyone was disappointed by the previous update I believe this one should make it up to him tenfold.
