Well, I just finished my first complete playthrough of this game, on the Sky-only route, and... wow. I really see where all the praise comes from now. This game started out as a watered-down midway between Once in a Lifetime and Eternum, and ended up as the most high quality, memorable, nostalgic, and creative story I have ever seen in my 12 years of gaming. Kei might just be a better written protagonist than Orion Richards, and I love that guy so much that I have him as my profile picture. So that's saying something.
And now that I've played through the full game, I want to talk to JaredX. I have some questions for him before I start my next playthrough. I know he'll reply to this, he is a dedicated guy. More dedicated than even Tanxui is to Eternum, in my opinion.
