This story provides a good balance of plot/technical aspects (e.g. power growth, descriptions of magical plants being made) and character interaction (talking to side characters).
This story's main pitfalls are a tendency toward sexist portrayals of female characters (e.g. women are all schemers and a character is a schemer because she's a woman rather than because it's a unique character trait or something resulting from her past) and a tendency for the story to - even with a single chapter - state that a character knows something and then later have the character express shock at learning that same fact or something easily derivable from it for the sake of drama.
In my opinion, this is a well-written story that emphasizes rational characters and dungeon-building that isn't just ecosystem balance with occasional intruders.
Style & Grammar: The style and grammar of this novel are about on par with normal published novels. The writing is readable, has proper capitalization and punctuation, and avoids both run-on and clipped sentences. While it could of course benefit from editing, it's decent enough that I can't pick out any places in particular.
Other people are upset about the paragraph length but, if one believes that a paragraph should develop a single idea, this is the mark of decent, thought-out writing. Shorter paragraphs are more concise and better for action & dialogue-driven stories, but dungeon stories are more about descriptions, ideas, and emotion than action and dialogue.
Also, while this may be a website born from translations of it, LMS was hardly concise. And, honestly, most of the short paragraphs on this site just come across as bad writing that was jotted off. I'd rather have decently written web novels than shitty light ones.
Story - Decent quality dungeon building. Because of how the MC was dragged into something at the end of the most recent chapter, it doesn't look like a story where the MC will become OP, nor like one where the dungeon basically just becomes separated from the rest of the world, nor like one where the dungeon becomes an individual - aka non-dungeon - that swears it will start a new academy after it just forms a harem.
Aka, it's a dungeon story where, hopefully, the outside will matter more than as a source of invading paladins that will be rage-stomped by catwomen.
Character Score - Decently fleshed out/backgrounded comrades; MC tries to act rationally but also displays emotions. He does act impulsively sometimes - whether due to anger or due to mistaken assumptions. Additionally, his regret when he acts impulsively doesn't always come across as real. This problem tends to be resolved by later flashbacks to what he was like before, but honestly shouldn't exist to begin with. Maybe more physicality w/ the guilt? Idk. Basically, his impulsiveness just feels distant, and therefore somewhat contrived, despite the author's attempts to make it credible.
But in general, everyone has a decent background setting up their actions, and the characterization will be decent as long as the author focuses on how these backgrounds would color their actions and choices.
In general, this is a well-written dungeon building novel that anyone who cares about such things should read. The only regret I have is that the author appears to be on hiatus, or dead due to a broken arm.
Read it on the author's blog; more chapters, very very good.
When I saw this a long ass time ago in the “Latest Updates” section, the title and a glance at the summary had made me assume it would be yet another dumb, overblown story about a guy reincarnated as a goblin who then becomes OP. Aka, another Re:Monster fanfic. Instead, as claws8367 says, this really is like a real, decently written fantasy novel. It follows the typical evolution plot (and might be at risk of monster-evolution’s tendancy toward meteoric rises, and a resultant lack of actual struggle) but has far better characterization, strong worldbuilding, and an emphasis on rural life. It will be interesting to see how the author includes tropes like magic crystals (e.g. ones found in slimes), evolution, magic formations, magic and industry, etc.
Spoilerish Background So Far: A goblin from city sewers is kidnapped, trained as a slave, incidentally freed by bandits who were raiding a caravan. Taken under the wing by one of them, taught how to survive in the forest, evo’s into a hobgoblin which edges him from lovable scamp to slightly badass. The main char’s background is fed in relatively gradually; the characters are somewhat decently characterized (a couple of important characters don't have much of a background yet, but it's still early, and that might be a conscious choice); the writing is somewhat annoying in that it’s neither constantly third-person omniscient, nor constantly third-person limited, but it's ignorable and always serves a purpose; the world's history is basically like the invasion of America by Europe, but with magic and west-to-east.
