Fatal Darkness

Fatal Darkness is a Flash screamer made by MJBDiver on 2004.

Flash animation
The Flash first displays a cartoonish window in a dark room, with the window visible due to the moonlight outside. After a while of this happening, a blank black screen will show, and after the suspense, the credits roll, where you think you're safe, but then a ghostly face appears with a scream pops up before the replay button shows.
