Cagara may be big, but it ain't brilliant. Sure, it has three or four different types of screen. The hitch is they are Sabre Wulf and Atic Atac-type screens coupled with a massive maze.
Your on-screen persona is a silver sphere in which you've been trapped by an evil gypsy. You're probably a sphere because the programmers couldn't animate a figure properly. The mission is to find the Chalice of Cagara. You also discover other useful objects to help you on your way such as a cross, a key and a castle.
One character-sized blob will speed up your progress while another - which does look something like a castle - will take you from the doorstep of one fortress to another.
Your ball is accompanied by a rabid, red, hampster called Eric who will attack any marauding monster blobs when dropped.
Mazes are the most difficult areas of the game from which to escape monsters. They travel at nearly twice the speed of your own jerking animated movement and they can float over the walls of the maze.
One nice touch is that some mazes are masked so you can only see one move ahead at a time. That way you can't see the monsters until they're upon you which is more interesting and, incidentally, it's the only aspect of the game I really enjoyed.
The mazes, which try their best to look three-dimensional, are all of a similar construction and you will probably give up, like I did, long before you get out of one.
