I finished the game as well I my opinion regarding point 1 is quite the opposite. This game doesn't need any choices at all. There where what, two or three max? And that is exactly why this game is SO good. The dev can concentrate one on extremely good storyline w/o having to worry about 20 paths like some AVNs do.
This is why it's probably the second one of a very long list in which I read every single one of the 260k words. It's just that good. I get wanting to make choices but just think about how captivating the story is.
