I'd just like to say one thing as my first impression: wow.
After just playing a small portion of the game (through the main titles/credits), I'm amazed. Its musical score is fantastic, graphics unbelievable, and controls interesting and somewhat realistic.
Spoiler:Also, whoever made the decision to have people fold the paper crane with the insert was brilliant!
I'll say more when I've gotten further in the game, but color me impressed--already.
