Solid story for the genre. Decent world building in the initial 100 chapters. Lots of possible tangents the story could take in the future.

First 80 chapters are solid. Feels like the author is planning to explore a larger world setting than they initially mapped out, and are growing the world in the middle of the story. Still a fun read.

The good:

Core concept is cool, and has lots of potential.

Writing is fine ( at least the english translation of it is ).

The bad: 

32 chapters in and we haven't even finished a week of the story line. Way too slow on the development front.

The concept is good, but the execution and utilization of it is middling at best.

Did I mention the slow pacing ... I'll come back and re-review when there's more chapters hopefully it'll get better. Again the writing itself is fine, and the core concept is quite interesting, just the pacing and utilization of his system is really sub-par.

Up to chapter 400, and it's very entertaining. The first 100 chapters the author was finding their legs, and coming up with the right mix for the story. I almost dropped it because the quality and story was starting to veer in too many directions, but they've finally found a path and a voice for the story. It's been quite enjoyable for the past 300 chapters.
