The premise of the story is quite unique and interesting. The story itself is good, but it's nothing amazing - as you would expect of a shounen. It's a standard survival/crafting/exploration type of story, one which some would even call "Minecraft manga version". The plot resolves around the MC trying to rebuild civilization from zero. He builds different modern-world inventions and defeats or befriends the enemies, using those scientific inventions and his well-planned tactics.
It's also important to note that all of the science presented in the manga (apart from the sci-fi stuff) is real and was actually consulted with a scientist, so you can learn something interesting from reading it.
Art - 8
The artstyle is very unique and quite detailed while also being very expressive, which helps a lot, as the series has a large amount of over-exadarated facial expressions, gags and other comedic elements. The character designs are well-done. They're unique and easily distinguishable from each other. Also, there's the "MC has wacky hair" trope, but it's been done so many times in manga that I don't really mind it.
Character - 7
The MC is very intelligent, but has some flaws and is quite likeable. Most importantly he doesn't feel generic, which is a big upside. The side characters are well fleshed out, but aren't really complex and overall there isn't much development, aside from "bad guys got defeated so now they're our friends". The first villain has unrealistic ideals (trying to establish a "perfect society"), and the second one is just a generic power-hungry jerk type of villain, but that's excusable, because the series isn't meant to have much depth in the first place.
Enjoyment - 10
The series features a lot of comedic gags and over-exadarated facial expressions, which made me laugh a lot while reading. I really liked the crafting of different accommodations, and the adventure element in the story. I also enjoyed the outsmarting tactics, and the elements of suspense in the final battles of each of the story arcs.
Overall - 8
This series is definitely good and likeable, but it's not a masterpiece. It's a typical (but not generic) shounen manga with simple story and characters. It doesn't feature any complex and groundbreaking ideas, but it does really well the things it should be doing, so that why it receives an 8 from me in the end.
