If you are looking for a great point and click ghost story for Halloween, I really enjoyed Goetia. You can play a one hour demo here. I believe it is only available at STEAM.http://playgoetia.com/
I wondered what the word Goetia meant... from Wikipedia:
"Goetia is a practice that includes the invocation of angels or of demons, and use of the term in English largely derives from the 17th-century grimoire The Lesser Key of Solomon, which features an Ars Goetia as its first section. It contains descriptions of the evocation of seventy-two demons, famously edited by Aleister Crowley in 1904 as The Book of the Goetia of Solomon the King."
