Well, you certainly didn't even try. So much for that "labyrinth" comment I guess.
Moving on, intricate is hardly a quality I'd attribute to TP's dungeons considering how linear the progression actually was. Mark Brown highlights this aspect pretty well - you follow a path to the left and back, then to the right and back, then straight ahead to the end and it's all compounded by equally linear key unlocks. Nothing about the puzzles within each room are particularly challenging or require the kind of lateral thinking and problem solving that MM's dungeons contained.
