Wizball is a shoot 'em up written by Jon Hare and Chris Yates (who together formed Sensible Software) and released in 1987 originally for the Commodore 64 and later in the year for the ZX Spectrum and Amstrad CPC. Versions for the Amiga and Atari ST were released in the following year. Wizball was also ported to IBM PC compatibles (CGA) and the French Thomson MO5 8-bit computer.
Wizball is set in the once colourful realms of Wizworld, where the evil Zark has stolen all the colour, making it dull and gray. It is up to Wiz and his cat Nifta to restore it to its former brilliance as Wizball and Catellite.
