I am amazed by the complexity of this story. I love how the author create a whole new world with its own rules and challenges on each floor. Each floor are uniquely different from one another.The artsyles at first are not the best i see but it gradually improved. The conversation is not overwhelming. It's very simple, direct and easy to understand.

The story is however heavily focused on fight scenes. You might feel suffocated from reading the never ending fight on each floor. The pacing for this story is slow in the beginning but once the ''plot'' kicks in, boi it kicks you hard.

Each side characters equiped with their own background stories with their own purpose and not just exist there as ''extra''. The main character is however quite the opposite.He has no background story, no bursting personality but as the plot moving, he developed from 1D character to a character with his own sense of feelings just makes me proud. It's an entertaining manhwa. You wont regret reading it.
