I saw the title and couldn't resist, given my name here on NG. It's 3am where I am now, so I'm in no state to write one of my typical crazy-ass hits-the-character-limit reviews for you, but in my half dead state this sounds pretty nifty. I do love 8 bit music in all its forms and variations.
I don't know if you portrayed your theme extremely well, though... To me it sounds more like, to relate this to a gaming or movie experience, the feelings of someone who has nothing left to lose and takes whatever final step in their journey knowing full well that they will die in the process or some such. I can hear some of the "betrayal and deception" you said you were aiming for, but it seems to be hidden under a couple layers of other emotions.
Nonetheless, it is a solid and powerful piece. If you'd like a "real" review from me, send me a PM and I'll get around to it when I can.
Power to you, KgZ.
