DREAM WRAITH: An interactive horror "annotation game"

Dream Wraith is a very clever and genuinely spooky "horror annotation game" produced by two English gents who call themselves the Camcorder Bandits.

What's an "annotation game"? Well, you know when you're watching a Youtube video, and suddenly a little gray square will pop up in the clip, telling you to click it? Annotation games use those pop-ups to create elaborate, interactive little movies.

I think the genre is still fairly new, and nothing I've seen compares to the ambition of Dream Wraiths. Be prepared to spend the next 45 minutes or so frantically clicking around, trying to escape from that damn thing.
