Being a huge fan of the author's previous work, Omniscient Reader's Viewpoint, I instantly jumped to read this series and have been following its chapters as they are released. I have not read the light novel, so this review will be based on the manhwa only. Think of the tower from SAO, but there's multiple of them and they appear in major cities all around the world, along with giant monsters that wreak havoc on humanity. Select people from each country, known as Tower Walkers, are summoned to complete all 100 floors of the tower in order to save humanity from the monsters. Then things start toget interesting. The story quickly introduces an item called a "Stone of Regression'' that can be found in the tower. These stones allow the user to regress in time and restart from the beginning of the appearance of the towers so that one can fix their past mistakes. The protagonist, Jaehwan, loses comrades either by death or regression, but still chooses to continue his climb, vowing to protect the present timeline no matter what.

I'm having a fun time reading this series so far. The art is jaw droppingly gorgeous and the story is pretty captivating as well. The big twist that is introduced in chapter 5 is pretty unique and makes me excited for the future of the series. So far, the characters haven't had much character development, but they are still enjoyable. If you're looking for a good power fantasy with some interesting plot elements, I would recommend trying at least the first 5 chapters of this series to see if it's something you might enjoy. It isn't on the same level as something like Omniscient Reader, but it is quite a fun read. I'm interested to see how this story develops!
