Recommendations for a Tower Climbing/Dungeon Descent like this?

Recently, I caught up with the released chapters of The Tutorial is too Hard, and I was pleasantly surprised by this manhwa. In particular, the aspects I liked most about this series are:

  • The MC is actually faced with challenges that cannot be solved just in a blink of an eye;
  • Things don't always end with a happy ending (floors 17th and 18th are really something), there's drama here, and a lot of it;
  • Secondary characters are well-written and play an important role for both the plot and the psychological development of the MC;
  • The story focuses on the Tower climbing itself, it's not only a background.

Can you recommend me something similar to this?

As for the Tower Climbing/Dungeon Descent that I already have read, there's a list:

  1. Level Up with the God (it's ok, even if the MC is on the too-much-overpowered side);
  2. Second Life Ranker (often a bit confusing, but a great MC. Secondary characters are underwhelming)
  3. Solo Max-Level Newbie (good art and good characters, I like it)
  4. SSS-Class Suicide (probably my favourite in every aspect)
  5. Pick me Up (love it too, probably it starts to have a bit too much plot armour after the first 50 chapters but still a great manhwa)
  6. Player who can't level up (not my cup of tea, I hate when the MC is "The Chosen One")
  7. The World After the End (dropped after the first 20 chapters, its writing is a lot confusing and I wasn't understanding what was happening on screen)
  8. Dungeon Odyssey (the art isn't great, but it excels in every other aspect, really intriguing in its darker and heavier tones)
  9. Surviving the game as a barbarian (even in this case, not a great art, but it's great in everything else)

I still have to read Tower of God, but it's intimidating with its 600+ chapters haha
