I love how this takes such a strange turn when you think it will just keep on in a more typical type of story. The whole gamifying his existence in this world was very unexpected.
I have only one real complaint with it in general is the times they have to obviously power scale Jin-woo. That said with even the best stories that kind of thing is always going to be a bit clunky.
I finished season 2 last night and I can say fairly confidently you will likely enjoy it despite that stuff, I know I was able to look past it anyway.
