You know, I've been thinking about writing a review, but I fear it's going to be a rather lenghty one, perhaps even a bit nitpicky. One think I will say is that the game suffers, at least in my opinion, of two things:
1. Having a very touching and bittersweet storyline under the mask of a sex game. There are times when it almost feels like the game would be better off having all the sex occur offscreen. The 'sexy parts' are just that, um, shall we say... jarringly, uh, written, compared to the rest of the game. If someone made a PG-13 edit PG-13 of this, it would elevate the game to almost perfection for me (certain questionable choices dialogue notwithstanding).
That is not to say that you can't have something like this can't happen in real life. You know, having crazy sex one day and making the hardest decision of your life next. It's just that a more realistic take on sex would have the characters moving and talking less like pornstars and more like, well... average people (awkward movements, pauses, journeys to the bathroom while the middle of finishing the act, and jokes included) during said sex scenes.
2. Forcing you towards a certain path even even if you don't want to go that way in your replay (or your first play, even). Though I get that you can only have so much 'branching' before the plot gets away from your hands. Some events are necessary to carry the story foward, even if you have to deprive the player of some autonomy.
Anyway, as a (probably crappy) amateur writer myself, I think I can recognize when an author puts his heart into a certain piece or work, so kudos to DPC for making this game and letting us experience its story.
