At the start, u was really hyped up cuz it's Pokemon like stuff and it's KillerHemboy, however, as I progressed, I don't remember at what point maybe like chapter 40 ish, I felt it was a bit childish. Though there are a few things that point against this, I could not help but think that this book fits someone of a younger age ( I'm 18 ). It really felt like I was reading a children's book. The reasons being most of the time everything is too too lax for MC, secondly, it is incredibly slow paced, actions of MC could've been more mature, it's a post apocalyptic world ( almost ), but almost everything seems to be happy happy.
However, I would like to point out that I may be very wrong, as, since it is an extremely slow paced novel, it may be very different in the future and needs time. Which for me, is irritating. Hence, I dropped the novel. Try it and if you like it that's all well and good.
