I love this game to bits! Even if it's just a demo. The music is beautiful, as is the art. I love the suspense, distrust, interesting setup and overall theme. Allaya's dialog hits a little close to home for me, she reacts in almost the exact same way I would :). I'm curious to see how this plays out, what they're holding back... I can always guess, but I'm sure you have a good amount of surprises in store ;).
I can't pick a favourite between Xei and Stefano >~< but Sean seems very interesting as well...
It's safe to say I'm positively hyped to play the full game!
