Crystle Castles, or Ice Castles as it is also known, is a straight copy of Atari's Crystal Castles
. Your hero must pick upp all the dots (crystals) spread around the isometric castle-like mazes guarded by deadly creatures. The concept is a bit like a three-dimensional Pac-man. Some paths and platforms require you to take a lift to reach them, and some levels also have tunnels between different parts of the screen. The tunnels are a source of confusion, since you can still see your character as in plain daylight while traversing the tunnel. Most levels are picked straight from the Atari original, though notably lacking the opening maze where the landscape spelt out the name of the company whose intellectual property was being infringed upon.
