Casper is a collection of six mini-games based on the 1995 movie of the same name. Casper is a ghost with three evil uncles who have turned Kat's father into ectoplasm, and the goal is to bring him back to life.
The gameplay involves completing various challenges in increasing difficulty. The six mini-games include:
Protect the Ooze: The player must protect the Ooze containers from Casper's uncles who are flying towards them. If the containers are damaged, the game ends.
Ooze Runner: The player must collect four Ooze containers on different floors while avoiding the uncles. A flag on the top floor must be touched within a time limit to complete the level.
Return the Books: Casper must bounce books to collecting containers using his trampoline ability, while avoiding Ooze vials that need to be collected.
Puzzles: The player must construct a machine by switching items into the correct order.
The Up and At 'Em Machine: Kat is pushed left and right in a mining cart to avoid chains and ghosts.
