Writing quality :
So far so good, I did find a couple of mistakes, but they are really small, and rather than mistakes it's more like the author forgot to type a word. Still, excluding that, the writing quality is nothing short of good.
Stability of updates :
Can't give anything below 5 stars since so far the author has been really stable with the updates. It has to be noted that the story is new so I can only give it 5 stars, Hopefully, the author remains consistent like this as I really love this story so far
Story development :
The story only has 7 chapters so I don't have a lot of material to make a proper judgment, but all I can say so far is that the story is really good I am loving the way it is currently going.
Character design :
Again only 7 chapters, but in the first 4 chapters, we can an in-depth description of the protagonist, Arthur.
World background :
Same as the previous three. I mean, you can't just build a world in a few chapters. But, I will still give it 5 stars since it seems like the story is going in the right direction. I have really high hopes for this novel as I really like author previous work Goblin feast
Overall - 5 stars. This is my opinion after reading 7 chapters. Really good stuff.
