This really brings back memories. I loved this game as a kid.
Anyway, your movie is very low quality. Here's why:
First, you shouldn't have collected the money because it doesn't add anything to the movie but makes the score screen last a lot longer.
Second, the constant spinning in the vertical sections gets real annoying real fast.
Third, the level 3 boss should've been manipulated into coming down more often.
Fourth, in level 5 (the construction yard) after a veritcal climb you collect some chests and don't get the screen moving as early as possible.
Fifth (this is the biggest mistake you made), the boss battles look extremely bad. You don't shoot the bosses as soon as possible, you sometimes wait long periods of time before shooting again. You should be sure to shoot the boss exactly as he stops blinking and becomes vulnerable again.
I only watched up to level 7 or so but I'm with Xkeeper on this. Even though the game is extremely fun to play, it's not so fun to watch, mostly because it's very slow. I don't think anyone should attempt to make a TAS of it.
