So let's break my thoughts up into a few sections. Firstly let's get the "game" aspect out of the way. Satisfying when it goes right, but incredibly punishing too, I had to switch to easy not too long afterwards. Maybe it comes with practice, but right now it's the only thing stopping me from playing the game over and over again.

The story, and the moral interactions. On closer inspection it does seem to follow the Hashino persona mechanic of having a couple of timeslots to interact with people in, however I think it's done in a very natural way that makes you want to play the game naturally. The texting mechanic is also a great way to allow you to really shape Vincent's actions, as indicated by the mysterious meter.

I think the one issue I have is that morality and feelings are muddied a bit.
I answered mostly because I felt Vincent was the dick here by not fessing up sooner, and I think it was entirely fair he got the Katherine ending. But a lot of why I ended up leaning towards her ending were just the good dialogue choices- like trying to stop people losing hope during the nightmares- it doesn't necessarily correlate with the character Katherine especially, but the game decides that hopeful dialogue corresponds to stability, when I don't think it does.

I do like the idea of Catherine representing hedonism, Katherine representing stability, and Vincent representing freedom, just a tad disappointed that some of the options didn't always correspond to that. In my opinion it might have been better to only have the mysterious meter be affected by decisions directly correlated to law/chaos. Of course, I might just be missing the nuance to some interactions.

That aside, I think this game was extremely successful in exploring love, lust and freedom, and if it weren't for how tough I found it, I'd be going back for more.
