Scary O___O
I will give you kudos for making a real event scary even in flash format. The overall way it just scares the user is also good.
The graphics/animation was superb and you did excellent there. The English subtitles were a real help here so that other users could understand what was happening during the story. However maybe adding voices would have been nice and instead of a DJ scratch for sudden turns you could have used a real light knife rubbing sound.
The story was quite scary to admit. At first he delivers a package to someone. Later he feels a strange urge to head to the subway where he thinks he is chased. Later he waits for the train and the creepy red eyed girl in a dress smiles at him before killing herself.
The audio was really nice and kept the viewer scared for the most part as well.
Overall, scary yet awesome.
