Quabbalah is best described as a psuedo-3D sideways scrolling game with problem-solving elements with a bit of ladders and ramps thrown in.
Quabbalah is the ancient Hebrew estoteric doctrine for an acolyte wishing union with his godhead. The Quabbalistic system is based on the Sepher Yetzira - the tree of life. To attain the unification with the godhead you must pass through the ten spheres of enlightenment.
Basically, what all this drivel refers to is a ten screen game where you must pick up objects in each area whilst avoiding the baddies sent by the Qliphopth (the anti-tree-of-life).
The graphics are of a reasonably good quality despite the nature of this isometric projections type of 3D display. This makes everything look a bit strange as there is no perspective in the graphics at all.
Your little man can move through four directions and jump. The 3D effect is very good and moving behind other objects and behind walls is handled very well, there is even a swimming pool that you can jump into - leaving no trace above the surface of the water - and then jump out again.
Whether you like this kind of game or not is up to you - you either love 'em or hate 'em. There are however, better games of this style.
