Bah...
I really like how it turned out... I watched it, with the intention of being alarmed, and yes, it works. I'm not particularly phobic or impressionable, I just made sure I watched it without the 'oh I'm big and tough and can't be scared' mentality. I mean, sure, if I watched it with a scoffing outlook, it wouldn't have had an impact, but since I was just watching it and riding the emotional rollercoaster, I enjoyed the sensations of worry and fear it stirred. As for improvements, yes, sound would be a plus, but not necessary. And don't tell people the intention is to scare them, because then they'll start going 'pah, nothing scares me.' and the effect will be ruined. But don't take the other extreme and do what that one reviewer said (the whole rotten-com and scream sound fx), because that is lame and overdone. =)
(Graphics) Well drawn, in terms of getting the point across. Yes, I agree with the guy before me, STICK FIGURES?
(Style) Originality is worth kudos points.
(Sound) No sound... sniff...
(Violence) Some creepy imagery and threatening stuff...
(Interactivity) None?
(Humor) None?
(Overall) Good flash, work on it, but damn better than what I normally see.
