I think it was less impressive than Tetris because of the lack of decision making, but that was still very very insane. I liked the fact the guy said he made the notes scrolling faster to not have time to think and just let pattern recognition and muscle memory play through the songs!
Anyone know why the arrows have different colors to them by the way?
The run of Talos Principle was also pretty amusing for someone who played the game, because all the dumb exploits I tried to do when I was stuck on puzzles (jumping off items, stacking stuff weirdly, jumping off slippery scenery geometry, clipping through energy doors) and that never worked for me, the runner did about 10 per minute for more than an hour!
