One of the challenges in Portal was to try to complete certain levels while taking a minimum number of steps. Obviously this requires good use of portal placement, but I was never able to get anywhere close to the goals. I don't want a walkthrough for the specific levels, but could someone give some general techniques that you use to complete these type of challenges?
