I have read up to chapter 20 so far, and plan to continue reading.
Let me begin by stating the problems with this work: it has a slow start and the enemies so far are fairly basic. The first 6 chapters are very slow and are pretty much just there for world-building purposes. The enemies so far are basically just goblins.
Now, onto singing its praises! The combat is interesting and has a visceral feel you don't get in many other works. You really get the sense that there's a lot on the line, it's a fight to the death and one wrong move could easily spell someone's demise.
The characters are very interesting: they have unique personalities with a fair amount of depth and the author is good at showing this depth rather than just telling us about it; I'd even say he's exceptional compared to the other authors who write about "some people transported to another world." The MC in particular feels very real, in particular when it comes to trying to come to terms with his harsh reality as well as realizing his own weakness. Personally, I find that I really "care" about this MC, which does happen in other LNs, but is a very good thing nonetheless.
Additionally, I feel like this work is showing a kind of story I haven't seen much of: the story of the people outside the spotlight. The protagonists aren't a bunch of Ichigos and Narutos, the world does not revolve around them; they are not the saviors of the century's end, they're a motley group struggling to survive in a harsh world while slowly improving themselves and their situation.
I would definitely recommend you read this, at least up to when they fight their first goblin (chapter 8), it's certainly worth it.
