EDIT: Actually having looked at the chapter titles in Korean it does look like each individual Hell Level (from 1-60) is going to be described IN DEPTH (3-8 chapters per level, so maybe 300-500 chapters in total just flashbacks). I hope new people will be introduced each level or it would get boring fast. But the fact that he had to wait this long for a newbie at level 60 probably means there will be fewer and fewer people later on. And since none of them survived to level 60 it means any emotional investment in them is wasted as well, so I don't see a way for this to get much better actually. We'll see how the author plays it, but I don't have much hope that it'll get better.
======================REVIEW AT CHAPTER 13==========================

Pretty good so far. The start was amazing, but it got slightly tedious when describing Level 1 of Hell (I feel it spent too many chapters on that).
>"Life is a series of choices."

>A phrase I once read in 3rd year of highschool.

>Life truly is a series of choices.

>But what the f**k am I supposed to do about it?

>That phrase hasn't helped in any way for me to make better decisions on improving my life.

>Lastly are the misfortunate. For example, those who were summoned while riding a rollercoaster. Those who pressed Hell difficulty while they were waving their arms in the air.

Of course their survival rate was 0%.

>[Lee Yeon Hee, Floor 1 : Uh

am I in Hell difficulty sdalkhfiuoqrg. I think I pressed the wrong button. Please help me. HELP MEDSKLFJGLKG]

>I can feel her sanity crumble with each passing word. It may have been the greatest misfortune in her life, but for me it was my only ray of hope! Hoorray!

>Meanwhile, the Newbie's post received enormous attention.

>[Lee Joon Suk, Floor 90 : Uh

Hm, I. Uh

Cheer up.]

>[Lee Gi Suk, Floor 22 : Ah

mistakes were made. You misclicked and now you're in hell. FeelsBadMan.]

>[Goo Dae Ho, Floor 53 : Uwaa lolololol. Press the wrong button and into Hell you go lololol.]

>[Lee Won Ill, Floor 17 : Cheer up. The survival rate isn't 0%, it's just 0.01% kek.]

Not only is the dialogue great, the character relationships and interactions, even for a few short days, is also well written, realistic and gives you a feel for what the characters are really like, their quirks, motivations, personalities and you feel that even though they aren't perfect, they're humans and they work with each other to overcome adversity as a team. And you feel that they are likeable after all.
>Although It was only for 3 days, I thought I managed to make a bond beyond that of friendship with them. But, all I felt was a little sadness for them, only that.

>Was I the weird one?

>I don't know.

>f**k.

>Although my brain had calmly accepted the situation, tears flowed from my eyes. To think I could still cry even after all that sh*t that happened before.

The characters are really well written, you get a deep insight into the mind of the MC, how he thinks, his personality, his emotional state.
And yes, he is simple, he is like the average NEET, but the story did very well to capture those feelings and it makes you feel like you are right there with him, it makes him feel like a real person. Just your average frustrated but good-natured guy, not some one-dimensional otaku stereotype like in many Jap novels or some guy with a chip on his shoulder like you get in xianxia novels. Actually if Reincarnator did a flashback to 50 years ago when Hansoo first entered the tutorial stage I'm sure he wouldn't be that much different.
The number of chapters describing Level 1 was unexpectedly high, and at some points you do feel like the author is dragging things out a bit. But then again you get a better sense of just how tough Level 1 really is, and how much room left for improvement there was. It feels really realistic. There is a lot of potential for further chapters. However, I feel that if the story continues to be focused on only the MC for up to level 60 then it's going to be a LOT of chapters of him just grinding levels and that would get boring really fast so I'm hoping that doesn't happen.
Also I hope the story isn't only covering the tutorial level since there is so much more interesting stuff that could happen once he leaves the tutorial stage with probably the highest level in the world. It might be even more interesting.
We'll see where this story goes. There's potential for it to go either way so I might have to revise my rating later.
Mad props to LightNovelBastion for having good taste in novels.

He spends almost 10+? Years in the dungeon, is still stuck there, and seems to have worked out some/most of his emotional problems. And that's saying something.
If we all watched and accepted that the protagonist in "Old Boy" became mentally unhinged after being locked in a small room for 15 yrs, of course it's reasonable for Lee Ho Jae to have PTSD and a whole host of other anti-social/self-destructive behavior after 10+? Yrs of survival mode in hell difficulty that he cannot escape from.

Lee Ho Jae realizes that they are not just randomly generated enemies that he needs to defeat to progress. They are possibly real (or formerly real) entities that had their own backstories and were just leading their own lives before being pulled into the dungeon. MC develops real empathy for them.
That's an AMAZING concept. Previous game-isekai type stories (esp Jap ones) had at best friendly NPCs that were anthropomorphized.

is a female with a lot of talent that can somehow survive because she is really talented, really really talented, how talented you ask? Well the author said something along the lines "She qualified as a participant of Korea in the Olympic games as an archer, which is known to everyone to be even harder than winning a gold medal at the Olympic games."....

So the MC is Korean and he's pretty much the strongest person in the tutorial game. Cool. But then of all 'miracles', a beginner accidentally selecting the hell mode appears! Of course it turns out to be a beautiful young woman and of course she has to be Korean. (Talk about the odds when supposedly the whole human race is being gradually summoned.) She's also an archery Olympic gold medalist, she's so perfect right? A Mary Sue to be exact. It really pisses me off with how easy she gets it with how she has the MC's backing. Even though the MC went through hell she gets a lot of free passes.

Kirikiri is awesome!!

So, The MC was stucked at Floor 61, where he needs another individual to beat it as it has to be beat at the same time. He made a clone but it's useless and now he had Yong Yong the dragon but he's not sure if that will do. The archer woman was still at floor 6, it's the last time she made an appearance.

At C72, The MC was still at floor 12 so I will expect it will take a hundred or two chapters to reach the floor where he is at, floor 61.

And also, even though he's still at floor 61 he's already the strongest inside and outside the tutorial as he said that he's f**king stronger than the G-rank monster, which is the strongest monster outside the tutorial, who needs many of the best individual to sacrificed in order to slay it.

And many of the gods were interested to him that even the God of adventure and God of slowness made him take their test to be thei apostle.

Lobby, gets to heal up there even if an arrow is in the persons leg. Might just be tutorial though, idk.
