"Dungeon".
...
Why, man.
Just, what a disappointment. The story actually had really good world-building, attention to detail -- slowly introducing the reader into a modern world with some fantasy elements poured on top of it, properly explaining how the tech affects the body, etc.. Actually making it seem like the writer gave two thoughts about the world they write about, and then...
"Dungeon".
Just immediately gives off bad vibes about this story.
But it can pull through, as long as there's no "system", or "skillz", or "drops", or "xp", or any of that shit. Gamification and litRPG has their place, but not in this story. Not when it tries to sell off the idea of "magic in modern times". That'd be such a bizarre bait-and-switch.
