Got the Japanese version (Intelligent License) last year. The game is not like Intelligent Qube; instead, you have to manuever your character through maze-like rooms, figuring out how to get from one end to the other, while avoiding patrolling guards in the process. It's all puzzle-based; not stealth action or anything, so if you enjoy "action puzzle" type games, you'll like it.
I do find the recently-released game "Exit" to be somewhat like a 2D version of PQ, and IMO Exit is the better game.
