Challenging riddle from The Talos Principle
When I recently complained that Portal 2 was too easy, I have to say, The Talos Principle is challenging. For a solution that, if known, takes only a few seconds, I often have to wring my brain about the logistics for long long time. Here a nice screenshot from one of the easier riddles, but with great effect.
A great game, very challenging. A more length review will come when I have finished the game.
