Not bad
The idea was there, and after seeing Dog of Man nothing may surprise me :D
The music is annoying, it should be smoother. Creepy doesn't mean scratchy noise and feedback. And the graphics.... well, the arts and the animations weren't really good, you got details, but you could spend more time on perfectionning it.
Is the "excessive nudity and explicit adult themes, text and audio" only about the hanged men? because it would be mild for the nudity, and that's all, there's no sex, no sound, no text...... I mean, there's worse movie were you see a dick and they haven't got a red rating icon.
