I am writing this advance review after reading till chapter 36(44 and the omake and interlude).
The way you write is AWESOME.
The story is amazing wheter it is the overall plot or the drama and backstory of the character, the comedy and the pun that can make the spiders cringe, or even the slice of life days.
There are a few grammatical error in the story but that's probably typo or you were tired. Overall there aren't any error that broke the immersion of the story.
The character... Oh the character the way you write them makes them so realistic and full of life. They are not some cookie cutter serve only to make the MC looks good they give meaningful interaction, awesome backstory, and many more.
All in all this is a story that I will recommend to people to read because it turn a classic story about dungeon into something so much more. Give it a try will you.
