Cloud Kingdoms is an arcade game released in 1990 by Millennium Interactive. The game was released for Amiga, Atari ST, C64 and PC (DOS).
One day, Baron von Bansai stole a collection of Terry's precious crystals and scattered them across 32 kingdoms. Playing the role of the said Terry - the owner of the crystals - you will have to recover all the crystals. Traveling around the worlds, you'll have to look for keys - which open the door to subsequent sections, avoid enemies (e.g. billiard balls) and use bonuses located on the board (e.g. wings that allow you to move to locations that can only be reached from the air ).
Cloud Kingdoms are 32 worlds in which a certain element dominates, e.g. in the world of Arrow Kingdom - the dominant element are arrows that show you the direction of movement. The world of Ice Kingom, the dominance of snow - and hence - is very slippery. The world of Unseen - this is a world with no walls - here you have to find your way to your destination.
