Besides beating the current speed record, this movie manages
to fire as few shots as possible (the exceptions being the
boss levels, for good reason). Also, it manages to abuse
how the game detects where it lands (barely landing on
slopes above, when it seems you would not be able to).
Also, in levels 1, 4, and 5, where after you beat the
boss, the screen pans to the right, you're not normally
supposed to be able to move with it, but jumping makes
it so you can slightly (might not lower time, but it's
a nice easter egg).
Besides that, on many parts, like on level 4's elevators,
I make close calls, only by dodging.
