Cindy Pondillo, owner of the adventure game site Mystery Manor, has just launched Hauntings Of Myster Manor, a ghost themed first person view point-&-click 2D game:
"You arrive at your ancestral home which you haven't been back to for 15 years. Each room holds a spirit that has their own story that they will tell you. You must help free them from their misery, which is how the house holds them there. You do that by un-murdering them or bringing them something they want or desire. It is quite atmospheric. Hauntingly beautiful, as I refer to it, but not falling into the "horror" genre."
Hauntings Of Mystery Manor can be purchased as a download or ordered through the official site. More detailed information, including screenshots and system requirements, are at the site.
