I played this game on a school computer every day before class started; sometimes even getting my parents to drop me off early just so I would have more time to play it. At the end of the year the teacher gave me the CD it came on. I still have that disc but computers these days don't have slots for physical media. I would love to play this again, some of the puzzles were quite challenging and I remember the sense of accomplishment in finding the optimum solution.
