A fun read. If you enjoyed the first book, you'll likely enjoy this one as well.
With the "tutorial" completed, Carl and Donut arive on the third floor of the dungeon, where things become a bit more complex and intense. New (to the series) concepts like quests, glitches, and exploits are introduced and things move along at a more brisk and consistent pace, which made the overall read feel tighter and more focused for me.
I still have some issues with certain aspects of the storytelling and some of the recurring elements felt just as overused as they did for me by the end of book one; however, I again found a lot more to like and will definitely continue the series at some point.
This will probably be a one or two book per-year read for me as I feel a little time and space between each volume will enhance my enjoyment of it and negate the fatigue from the more repetitious elements, which I'm now certain would sour the experience in my case if they were binged.
