Making a good puzzle game can be difficult. First you have to figure out a good mechanic for solving the puzzles. Then you have to design puzzles that can be solved with the mechanic, offers a challenge, but does not frustrate players. Quantum Conundrum, developed by Airtight Games and published by Square Enix, has done a good job in puzzling this together. In Quantum Conundrum you have been dropped off to visit uncle, only to find him missing. He is somewhere in his house as he helps you through the game, with varying degrees of usefulness, but does not know where in his house that he actually is (it is pretty big). Well, time to save the crazy scientist.
