This was an interesting story.
I liked how it focused on the development of different kinds of torture devices.
But I especially like how each of them was described from both an artistic and a painful perspective, with pros and cons.
The final act was also very horrifying, and I loved it even if I saw it coming from a mile away.
The execution of that ending made the experience of this story worth it.
The only thing I had a problem with was the middle act of the story.
I felt that the pace suffered from the repetitiveness and redundancy of some of the events there.
