Amazing concept so far. Just one question: The guy with the glasses; did you get the voice actor of the -Trapped- series to voice him? Sounds reaaaallly familiar, and I wouldn't be 'too' surprised since Episode I was basically an escape game turned into a flash video.
Your incorporation of the subtle, yet still very present humour is a great touch to foil the relatively serious mood of the video.
I'm not sure if it was intended, but the way you presented Part I and Part II as ooposed to Episode 1 has a more dramatic feel to it. Similar to manga styles, which I take is at least a minor form of inspiration due to the storyboard-like drawings in the main menu.
Overall, great work. I'm really looking forward to the continuation of the story.
