The story is amazing! So many player choices. Some of the choices don't seem like they matters a lot, but that's the fun part added to the story. (Very engaging.) The first round I played it, I was surprised by the amount of choices(reactions) which are provided. I can see the game and the world is building in a very large scale. So the second round, I tried check how many endings will it possible lead to with so many choices. And I was again surprised that eventually they all lead to the same part (the grey man). Very thoughtful!
I think adding a little bit graphic or background would make the story even better, (or not) maybe just changing the fonts and colors of words. I think sound effect would work great with your game. No fancy graphic, but words and sounds. Would also be very interesting.
