Nice eerie atmosphere, the music and graphics really tie it all together.
The gameplay felt a bit unfair for me though. The hands grabbed the souls even though they appeared far enough away. Also, I wish the souls would follow the trajectory of the closest one (unless it's on purpose). In some places the passage appeared too narrow for me, and it would allow to not worry about somebody getting caught at the end of the soul-train (I don't have a fancy way to control them anyways).
Loved the overall experience, terrific job!
