Ugh the ending - I wished there was something else when it came to the foreshadowing. Also I think it hinders the character development of the main character quite a bit. Very clichée.
The main character annoyed me quite a bit, he's not very well thought out imho, seems like just another Harry Potter: Entitled, unthoughtful with a big portion of luck and a little clueless. Well a lot clueless. The motivation just seems so ... superficial.
I think without the references to games and stuff I'd given up much sooner.
The development of H was cool, but cut very short.
There was so much potential for a good character story, but it was rather like a 0-8-15 (boring, normal) game story, very one-dimensional.
