Slow start but lots of fun once it got going. Not literature, not even close, just an enjoyable dungeon crawl read with pleasing progress and some fun quirks and world building
I have some time today, so let me explore why I liked this book in a little more depth because it's not a book that most people would rate 4 stars of 5 on normal merit. Its characters are wafer thin puppets. Its world is a set for a play, not a real breathing environment. Its lead's "hero's journey" is delivered with "tell don't show (sic)". So on the surface this book is crap.
Now, let me explain why I thought it was a blast and why I can't wait for book 2: it's a lot of fun to read. The author knows enough that his set dressing is weak. Instead, he focuses on the tower and the dungeon climb. The floors feel fresh and imaginative. And as the hero works his way up, they begin to take one a bit more shape and respond to his character and to that of his companions. Starting alone, he soon gains two of them and then at the end a third, so there will be a full party by the start of volume 2.
The leveling system is "beat a floor, gain a level", so you can't just farm your way to extra HP at low levels. You're rewarded for risk and pushing on to harder bosses, which makes the story more engaging to read. Plus, the second Jack's given an overpowered item, you know it has a ticking "sell by" date, and it plays its role perfectly.
Jack's love interest is Boring McBoringface (and judgy to boot) but not so annoying that I put the book down. She's redeemed somewhat as the story moves on, as are most of the paper cutout towns folk. In fact, the world seems to grow more real as Jack faces down the enemy and pushes the edges of his experience to gain a wider understanding of his world.
Jack himself is Impulse McImpulseface because he has no real characteristics or flaws to bring to the table, but who cares? His job is to explain the game, play the game, and strategize the game and he does a great job of that. His interaction with his side kick, aka Exposition McExpositionface, is fun, light, and to the point.
This book also has one of the best Isekai reasons ever, one that allows all the superficially shallow things to make sense and support the story. The author isn't coy about this. Hints are dropped from the very start, and confirmed early. It's a clever approach and one that really added to my enjoyment.
And just when I thought the tower crawl was the main attraction, it turns out that the author also brought in settlement building! Even more fun.
So, while this is admittedly a crappy book of low writing quality and poorly developed characters, I'd happily read it again and am looking forward to the sequel. In the end, books don't just grow our minds and expand our thoughts, they also entertain. This one entertained and put a big smile on my face. I'm happy for that.
