I just went through the emotional rollercoaster of watching someone solve a puzzle live on video. It was a puzzle I helped write, so I was pretty much either yelling "no no no" or breathing "whew!" the whole time. (Fortunately I don't have a microphone attached to this computer or else my yells probably would have been pretty spoiler-y.) Cute Mage solved it 99% solo, which is inconceivably difficult to me, except that I just now saw it done. Anyhow, only watch this video if you're OK seeing spoilers for the 2020 MIT Mystery Hunt puzzle "Spaghetti Western" and are prepared to be amazed.
