Wow. That's awesome. I could recognize most of the movements from the video... Guess I played a lot of Prince of Persia back in the day. It's funny how the brain can recognize specific movements like that, or like when you can recognize a friend from far away just based on how they walk.
I remember well the movement that impressed me the most. The elaborate changing of direction when running and then turning. It looked so natural, and it was the first time I'd seen that in a game.
Most platformers still violate conservation of momentum and let you change direction in mid air.
