Blinky's Scary School

A cartoon platformer from the early 90's.

You play as Blinky, a small ghost who is the star pupil of the Scary School.  It's your job to rid the castle of all the ghost proof defences that have been setup by the ghostbuster Red Laird McTavish.  To remove the defences you must explore the castle, pick up various objects and drop them into the cauldron to cast magic spells.
