Casper is a mini games collection based on the 1995 movie of the same name. Casper is a ghost with three evil uncles, who have turned the dad of Casper's human friend Kat into ectoplasm. The goal is to bring him back to the living. There are six different mini games:
Casper features a range of challenges, including Protect the Ooze, where you must shoot the uncles before they damage the containers; Ooze Runner, where you must collect Ooze while avoiding the uncles on four floors; Return the Books, where you bounce books to collecting containers; Puzzles, where you build machines by switching items in order; The Up and At 'Em Machine, where you guide Kat through a mining cart while avoiding chains and ghosts; and Casper Says, a simple Simon Says variant.
To complete the game, you must complete the first four mini games three times with increasing difficulty, before moving on to the fifth and sixth. The final challenge is a final Ooze Runner game.
