Crumble blocks can be jumped off of the frame samus lands on them.This is first used to save time getting a missile tank in NOC. Single walljumping is a combination of normal walljumping and morphing on the way back.Mega-X is killed in 4 shots by getting the flare damage inside of it each time.This allows samus to keep the shinespark for longer by crouching while approaching the ground. While speedboosting, pressing nothing for 1 frame, jumping for 1 frame, and pressing forward for one frame will make samus jump in the standing position.Morphing in midair repeatedly will cause samus to fall very slowly.Zazabi can waste no fewer than 3 jumps.Enemies touching the flare will be dealt extra damage, which allows for one-hit eye door kills before super missiles. The charge beam has a 'flare' that appears in front of it while released.Pressing left and right repeatedly while in morph ball form makes the ball stop spinning, like it's frozen.This can be helpful for killing creatures in a few spots. Firing missiles while running will bend them.It is faster to morph in midair because there is no morphing animation.

This is also true for morphing at the same time, except it fires at the back of samus' sprite. Jumping and shooting at the same time will make the beam/missile fire from the bottom of samus' sprite.Shooting 1 frame after pressing the opposite direction will turn samus faster.Spinning and 'unspinning' on crumble blocks will make samus fall through them faster.Jumping for 1 frame off of platforms on to platforms directly below samus save 2 frames each jump.Double missile shots on eye doors are only helpful before the charge beam is acquired. This does the same damage as 2 missiles at the same time. There are 3 things that are useful to hit at the same time with 2 missiles: eye doors, Core-Xs, and Eye Core-Xs.Any pause I make before a room is to luck manipulate the eye door to open its eye right away.I have 250 by the end, so wasting them won't hurt me. I like to abuse my missiles to make the run a bit more entertaining.Because all of the power-ups need to be collected, the game only measures percent by the amount of missile, energy, and powerbomb expansions picked up.I aim for fastest in-game time, even though there are only a few instances where this applies (like going through a door an extra time to build up the speedbooster).Here are some various notes about the run, listed in order of appearance.
