I haven't read the novels that you speak of so I cannot say anything about that. But if your main concern is the towers, floors, etc, there is actually a deep reason why the floors where created. If you happen to know the manhwa, "The Player Who Can't Level Up" you may somehow understood where this is going. But this one is also focused on the life of a regressor so it somehow gives the same 'regression depression' vibes as with Joonghyuk or Shin Yoosung from Omniscient Reader's Viewpoint, or with Thesilid from The Perks of Being an S-Class Heroine (a.k.a.Transmigrator's Privilege) and the moral lessons you can feel with Gongja from SSS-Class Suicide Hunter.
It may be confusing at first about the nuisances they experience on some floors but as you go read about the higher floors, especially the 8th & 9th flr (which I recommend) everything will make sense.
This book is just so amazing. I'm hooked and already addicted with the flow of writing. I swear, had I found this in a store , I would have grabbed it without any second thought. Loving it, keep writing more Author.
