Good song. It has a nice feel to it. Somewhat like a haunted house feel. That's what I get. I like it a lot. Although the piano has a somewhat harpsichord-al sound to it. That's probably what also contributes to the haunted house feel. Also adds a lot to the collab. I like.
P.S. Could you please listen to my collab submission? http://www.newgrounds.com /audio/listen/201029
