World 1 complete. This marks the end of the really easy stuff, so it will probably be much longer between levels now.
Consists of 4 levels and a boss.

Things worth mentioning.
In level 3, I have no idea why I was allowed to stand on those hovering platforms after performing the sword climb trick, but it really worked to my advantage. Normally, I would just fall through hovering platforms after doing that, so it was strange that it didn't do that. Also you catch another glimpse at the Fall Through Floors glitch, but I don't actually go the whole way.
At the end of level three, I crawled on the ground before getting the ring. This is because it wouldn't actually let me pick it up until she was done flashing, so I had time to goof off.
In level four, While standing on a switch, I jumped up to a really far platform that I shouldn't have been able to get to. While I'm not entirely sure how it worked, I'm about 85% sure it goes like this...
In a lot of games, your character can walk off a surface for a bit, and still be able to jump. (a prime example being Kine from Kirby's Dream Land 3)
This is also true in Lady Sia. Sia can jump while half off an object. For some reason, Sia can go further off the object and jump when on a certain sprite. The sprite in question is when her legs are farthest apart just so you know. Sia's walking animation always starts the same way, with the sprite needed being near the beginning. By letting go of the D pad button, (either right or left) she will slide for a bit. By doing this, you can reset her walking animation. I slid on the switch and was able to restart the walking, thus getting the sprite I needed at the right time to jump to the platform. This saved TONS of time seeing as doing the correct path takes a long time to do.
In level 4, I perform the Sword Climb Trick, and then get on the bird. This creates another weird glitch to add the list of glitches caused by Sword Climbing. Once I start flying on the bird, the screen is stuck on one area of the screen. This lousy description means that even if I fly down, the screen won't follow me to lower areas. Due to this, I have a very limited space to fly around. This can be fixed by getting hit by an enemy.
Boss fight went really well.
*edit* Oops! Sorry mmboss, I forgot to answer your question.
I'm unsure of how long the movie will be. If I had to place bets, maybe slightly over or under an hour. The first world was pretty fast, so I don't know if that trend will continue. I do know that the levels get longer each world, so it's hard to tell. By the way, there are four worlds.
I also never mentioned that this is a run without the bonus levels. Each world has a bonus level you can access by getting 100% on each level. To get 100% on a level, you have to collect all 25 of the green diamonds, free all 5 tied up people, and finish with full health and magic. (You have not seen any magic yet) This would be a much longer run, and to be honest, I've never tried to get 100% on any levels since it's too hard.
