Alright, I've gathered my thoughts -they were scattered and broken on the floor, which always happens when I get addicted to something - and here's why I liked it so much:
The way you go around town and talk to the girls is pretty fluid. The way the game kinda takes you by the hand and teases you about the next girl, encouraging you to meet them all, feels natural. The fact that you can't save on your own is a bother, but as a result the game is a lot on the forgiving side. You never really lose anything, so all you have to do is go for it. Besides, even if, like Kendjin said, you can see the girls' profiles on the internet or even in the game (second tab of their HunieBee entries), sometimes they'all ask you completely random questions you have to give some sort of a personal answer. And that's nice.
And And I'm a sucker for match-three, bejeweled, shariki, you name it. The extra strategy you need was like a hurricane of fresh air because it isn't bullshit like most game modes in Candy Crush. Gearing up with gifts is part of the strategy too, so it ends up being somewhat complex and actually challenging.
I'm kinda sad there is no closure though. I've reached a point I can win any date just having a couple passion matches and then flirtating (green blocks) forever. The difficulty curve is neatly planned until you get the last date with two girls, more or less. It gets far too easy then even if the difficulty keeps raising.
That and I would have loved some character development, especially for best girl Audrey. I suppose that's just how dating sims are, but it's kinda disappointing.
