This review is gonna contain spoilers so heads up
This is a terrible survival manga, the narrator or whatever is just annoying and points out the obvious as well as used as some sort of explanation for when the Mangaka does some really dumb plot armor sh*t like how he accidentally figured out how to make leather more loose and wearable among some other god awful contrived BS just to force some plot along. This isn't fun, exciting, intense or thrilling at all to read like a survival manga should be, there are no stakes involved no risks and fear for the main character because he
always finds some stupid unbelievable way out of any predicament he is in this dude pretty much killed a bear by accident and tamed a damn owl before that. It's ridiculous.
In short, The narrator over explains everything and seems to think you're blind or stupid and the main character never really works for anything everything just conveniently falls into place and it's just extremely boring. Even when the MC does do something like build a base of operations it just skips forward to when everything is pretty much done and off screens him making tools etc. The least you could do is show us him making it and how hard it was and the process of making etc. but no. It kind of just mentions or shows that he's gonna build something then we skip to when everything is mostly done or is fully complete. it's boring. Wait, this wasn't short.
Sorry for the short review but it's been about a month or more since I last read this and I finally decided to write a review for it since I was bored. I may come back after reading some more to add on to this and I may even go back and re read it to give you a better more detailed reasoning for why I think this is awful but for now i'm gonna leave it at this.
