Well I certainly didn't hate it.
*** Spoilers Ahead for those that don't want them ***
The new content was, of course, too short. But I enjoyed what was there. I love Kate and Lynx so I very much enjoyed their scenes and even though I am less enamored with Lisha I do still like her and enjoyed seeing her start to soften up more, become more affectionate.
The new girl, Aurora, got just enough attention that I have come to the conclusion that I like her. I look forward to seeing her part of the story develop.
I thought the changes to Marco's body and even his personality to a lesser degree were a pleasant surprise.
I'm sure there will be time for it later but I was a little disappointed that Rei didn't get much attention, they basically just bumped into each other and promised to talk to each other more later. For me that was disappointing simply because Rei was my favorite from Part 1 and if it were up to me she would have been the first person I would have gone looking for.
I very much appreciate that some of the settings and options were up for a reset at the start, even for my imported game. It's nice to have the option to change my mind on some things.
I have yet to try my full Harem game though, this was my partial Harem game, so I don't know if it'll be exactly the same. Especially concerning how Amanda, Jennaka, Vellany or Hannah reacted.
I liked that the story seems to have shifted to a 'new' threat right away, the Hengetis and the Villains and their attacks. That seems to be the short-term story hook while Thread and Miraculous Man (I think thats right) loom in the distance as a future major threat.
Theres also the hint that something is controlling the Hengetis, driving them to attack, perhaps a Queen or something. A new Hengetis lady made a very brief appearance but I dont think that she is the Queen.
All in all, it's a good start. If you can keep up the flow by making sure the amount of time between content releases doesn't get too ridiculous (over 6 months) then I'll be satisfied.
