went in such unexpected, strange and even disturbing directions its factor of not knowing what would happen next was even more effective. And the climax, my God! When the music kicked in in the fight against the real final boss I was simply in awe. I honestly wasn't expecting a fight against a transcendent, god-like being to not only feel totally earned, but also completely fit within the world and even more, being completely tied to all the central characters.

The section in the True Laboratory was genuinely unsettling and creepy, and gave the story even more gravitas. The music was absolutely perfect.
