actuall the demo was very good, the game showed much more potential in the puzzle department the jazz 2, the demo focused more on puzzles and the stunning effects of the time than blasting enemies. IMO that isn't really a problem, i like puzzles. It focuses more on trigger zones, muchos cool the game has much more potential than is really told. After trying it once i was stunned, i couldn't believe a game of that calibur in 3D had even been produced. If the game had been produced using the unreal engine and released today, it would still sell. Gameplay is just that good. Plus strafing adds so much to the gameplay
