Thank you for the feedback! I'm actually happy that you're going to do an LP of this VN. :)
1. The last time I did a test playthrough, it took me about 3 hours on average to finish each chapter. The latest chapter is about 4 hours long, and that's because you have two routes to follow for that.
2. The majority of it is story-based; that is, the first two chapters are both Kinetic Novels. You'll only start receiving options starting with the August Chapter.
Have fun with the story and I'll be looking forward to your LP!
