Casper is a 3D puzzle-adventure game developed for 3DO, inspired by the film of the same name. Players assume the role of Casper, the friendly ghost, tasked with befriending a new companion while thwarting the schemes of Carrigan Crittenden, who seeks hidden treasure in Whipstaff Manor. Casper must navigate challenges posed by his mischievous uncles and collaborate with Dr. James Harvey to achieve his goals.
Based on the Casper film, the game pits you in the role of the friendly ghost trying to make a friend and a second chance at life instead of scaring everyone away.
The plot centers around the `spoiled, grasping inheritor of Whipstaff Manor` - Carrigan Crittenden. She's after the treasure she thinks is hidden in the walls. Casper will need the help of Dr James Harvey - therapist to the dead - if he has any hope of succeeding in his adventures.
Casper will also have to deal with his uncles - Stretch, Stinkie and Fatso, who just love to scare `Fleshies` and thwart Casper's efforts. The gameplay is 3d - and is mostly puzzle solving, with Casper able to take a variety of forms and manipulating objects.
