I finally finished this game. All five chapters of it. And I have to say, seeing the game come to a close was a rather bittersweet feeling. I've been following this story, and these characters, for 4 years now. And I had my eyes on this game since before even then.
This game, while the plot does get a little... unhinged... in the last couple chapters, is a definite 10/10. The only H-game to have made me cry at any point in the story. Probably because this was clearly less of an H-game, and more-so a game with H in it. The focus was on making a fun game, enjoyable characters, an interesting plot.
And porn was something that, while nice, was entirely un-needed for the game, even if the nudity is a core gameplay mechanic. You could easily take the sexual content out, and replace it with more conventional gameplay systems, and it would still be a great experience.
I know that this comment is basically talking into the void, due to the sheer number of comments on this game, but I highly recommend this game to anyone who's contemplating getting it. And I also recommend supporting the developers for having made this. I lack the means to do so at the moment, but I plan on purchasing the game legitimately whenever it's fully finished and the kinks are worked out, however long that may take.
