Tried to make something out of this... nothing too serious. I'm expecting to get better as I'm going through the game, so this will probably be improved. That being said though, feel free to watch and comment on these first two levels.
Luke moves a lot slower while jumping than he does while running, so ideally I want to be in the air as little as possible. Even stopping to duck and shoot the box near the end of the first level is faster than jumping over it, to give you an idea. The only glitch I've used is the one Cardboard mentioned earlier in this thread; using Up+Down+B to use the lightsaber without having it. It's particularly useful against the boss in the second level, as it kills him in two hits.
IMO the game makes for quite a nice looking TAS, and it's only going to get faster with force powers.
