gareth commented at 2016-02-18 00:16:34 Far too hard for a daily puzzle - I had to give up since I couldn't spend long enough on it, and come back the next day. If a puzzle is extremely hard without warning then it's unreasonable to expect people to magically have enough time set aside at the moment they discover this. It also takes away the fun of it, and means those who don't have other commitments have a definite advantage. ;)
Good point. We plan to add a difficulty level in the next episode of CTC.
