This is my first time playing in almost 22 years. I had luckily forgotten most of the puzzle solutions and was able to enjoy this almost like it was my first time. The graphics are difficult to maneuver. Like many Sierra games, and LucasArts to a lesser extent, you get the feeling that some of the obstacles are meant to infuriate and lead one to using the now defunct 900 numbers. But all that aside it's a wonderful game that leaves you feeling accomplished when the greater picture finally clicks. The playthrough time of 7.5 hours is incorrect. I think you could spend 7.5 hours looking for a single missing piece of any one of the puzzles. I wish Oliver Brelsford was on Twitter!
