Very good, VERY good.
I felt it, I felt the emotion, and it was great!
Sad.... but great.
But I don't belive for a moment this is the end, which is a sub-effect I belive you where going for.
The way things are structured up to this point tell otherwise.
You also gave no indication of this ending in your comments.
It wouldn't make sence for this to be the end.
So... I'll be waiting for the next one.
Excellent work...

SHIT!!

This is one of my fave chapters. LOVE IT.

*cries* Sooonic.... wow im qute pleased with this story. Its detailed, and sticks with the game's storyline. I especcially like the way you blended this scene. The game never really told you how Sonic dissappeared from your side. I most interested on WHAT ending you are going to choose for this story ;) cause i know a few which include Sonic, i hope you choose the 'happier' ending though ^.^

Good Luck...

I must say, you're story is very good, better than alot of things on Sonadow recently, and much better than you seem to give yourself credit for.
There are no real flaws I can see, it's long, it's detailed, it's well written, it's action-packed, and you update at a brisk pase!
Nothing to complane about here!
Yet...
Anyway, keep up the great work!
