I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I picked up fault milestone one on sale. I think it's called a "kinetic novel." I'm at about 2 hours worth of reading time so far and I've only encountered one choice, and it had absolutely no effect on the story. Definitely more of a story with visuals, movement, and music than a game.
So far I think I like it. The artwork and music are great, and the story really started to grow on me once I got to Chapter 3. Unfortunately, the writing sucks. If it weren't for other factors, I doubt I'd enjoy the overall package nearly as much. An example from the part I stopped at for the night:
"However, luckily, due to her weak body, her body had rejected the mana before her body had taken a lethal amount."
Editors are important.
