In the game Casper , you play as the friendly ghost trying to make a friend and a second chance at life. The story revolves around Carrigan Crittenden, the "spoiled, grasping inheritor of Whipstaff Manor", who is after the treasure she thinks is hidden in the walls. You'll need the help of Dr. James Harvey, a therapist to the dead, if you have any hope of succeeding in your adventures.
The gameplay involves 3D puzzle solving, with Casper able to take on various forms and manipulate objects. However, he'll also have to deal with his uncles - Stretch, Stinkie, and Fatso, who love to scare "Fleshies" and thwart Casper's efforts.
