+Simple?  Yes.  Easy?  Certainly not!  Hidden traps, vast mazes, laser beams,
+and most of all, countless hairy puzzles usually block your direct way to the
+Oxyd stones.  Enigma’s game objects (and there are hundreds of them, lest you
+get bored) interact in many unexpected ways, and since many of them follow the
+laws of physics (Enigma’s special laws of physics, that is), controlling them
+with the mouse isn’t always trivial.")
