This is prooty good.
The animation quality is pretty good, and the idea makes for some pretty...interesting flash. I would say, overall, you did an awesome job. Having giving you a compliment like that, I do have some thing I should say. This kind of looks like the lovechild of F E A R and one of those Mr_Artist films. Try to squeeze some of your originality into it. Also, it is hard sometimes to see the characters. I understand the darkness adds to the eerie points of the flash, but I think that you should make a little bit of an effort to make the characters more visible. Other than that, keep everything the way it is.
Sincerely, (wow, that's a new one),
