The author created a character that would be OP in GOT and so he constantly nerfed the MC in really ridiculous ways. The mistake here is not creating a story in which the MC is challenged, but giving the MC an advantage and then nerfing the MC in ways that seem surreal and impossible when considering the MC's advantages.
The fanfic would be really good if the author didn't spend so much time claiming that the MC has the muscular memories of a 12-year-old shinobi at the time of the most conflict in the narutoverse and then constantly nerfing him. The worst so far was a moment where the MC was nerfed in a way to ignore instincts in the middle of a fight, even when he is thus far constantly using his instincts for everything and then resulting in defeat and near death against some normal bad guys.
Seriously author, if you want to give him difficulties, create a weaker MC instead of constantly needing to nerf him. Or use external factors to nerphalo instead of making the MC suddenly ignore his advantages like superhuman strength, agility, senses, reflexes and instincts. Personally for me the worst was a bruise on the leg impairing the mobility of the MC when even an ordinary person would not be affected by it during a moment of adrenaline.
-------------------------------------------------- ---------
Writing Quality: Overall it's good, but at one point there was a phrase in Spanish coming out of nowhere which really broke the immersion and that's why I'm giving it 4 stars.
----------
Stability of Updates: It's good, the normal webnovel of 1 chapter per day and for that I'm giving it 5 stars.
---------
Story Development: In general it's good, nothing too special and for a fanfic this would be enough for me to give it 5 stars, unfortunately NERFS occurs at critical moments in the story and that hurts the development a lot, that's why I'm giving it 2 stars.
------------
Character Design: It's a bit confusing, at one point we have an MC who by inheriting the body of a 12 year old Shinobi from the Warring States era was given muscle sticks, a battle frenzy and powerful instincts, but that only seems to work during the training. When the MC goes through a real fight he seems to forget all his superhuman stats and even the chakra boost stops working. This creates a contradiction where we have a paradoxical character that at relevant moments in the plot where these inherited muscle stories and memories should come naturally actually seem to drift away and be forgotten and that's why I'm giving it 1 star.
----------
World Background: It's too early for that, so far we don't have any problems with it, but it's expected and the real challenge will only appear when the MC gets involved with the nobles and politics. I'm taking one star off because in chapter 20 we have a sudden revelation that is really generic and seems misplaced, would probably be better fitted at a later time. I'm giving 4 stars in this category.
----------
Finally, I'm taking a star off every category because of the author's childishness, including insulting readers (he called me douch) even when we don't insult him and what appears to be a refusal to even consider most readers' opinions when it runs counter to his.
