00:41.617 frames saved over previous run. I'd originally made a run in 2019 but didn't submit due to lack of optimization. While I was leaving speedrun scene, new boss fight strat, rng manipulation and other small timesavers were invented. Those led good amount of time save and broke 1:03 barrier.

That page lists what events affect RNG. If you want to know handy way to manipulate, the answer is no. All you can is waiting for certain kirby's animation that changes RNG or external cause such as an enemy, loading other map.

Deceleration rate (for walking/dashing) assumes your speed is higher than terminal and not doing directional input. If you do, the speed is instantly reset to terminal next frame. I'm not listing irreverent data for this run. Pitch is a bird you can use via stone+cutter ability combo, which is used in 3-2.

You should usually avoid moving on both upward or downward slopes, they slow down your speed (except one instance I'll explain later). Touching wall kills all your horizontal speed except you are in underwater or riding DDD.

Once your speed goes below terminal speed, you hold d-pad for a frame then release it. You can stay over terminal speed for a while. As I showed, speed decay is weaker in mid-air than on ground. Best way to keep high speed when kirby doesn't have high mobility ability is jump and staying mid-air. But only requirement for this trick is being in mid-air, jump is just a way to do it. This trick works for Pitch too.

You can lift up an ability you held as an star object or lift up an enemy. But it halts your movement for a short time so not ideal for speed. But it can be cancelled by getting hit or transitioning right after doing the action.

I will add them later but I'm not mentioning small improvements that are just keeping better speed since it's unnoticeable unless you watch with speed value.

They are special vehicles you can ride in said stages. Those are affected by slopes like kirby too so jumping is fastest. But you start losing speed gradually if staying midair too long. That's why you see short hops for 4-2 and 5-1 specifically.

Boat's physic works partly different from two. While it's affected by slopes too but its max speed is varied depends on the angle of slope. The river map is consisted by various angle of slops and they give 5 different speeds as far as I noticed (10.0, 9.0, 8.5, 8.2 and 8.0). Big jumping can help to delay speed decay if you need to go through a slope which gives worse speed from faster one. This speed change doesn't happen for the minecart or the sled.

NiaHoshino and DarkRiolu27: For finding workable RNG from 3-1 through 3-Boss.

Curtissimo: For finding a way to carry fire from 6-Boss. For some reason, RNG manipulation couldn't have the boss transform fire form last like it's hardcoded.

WaddleDX: For sharing a list of all possible RNG variance at picnic minigame. It helped me to route the RNG from 4-Boss through 5-3.

Challenger: Claiming for judging.

Challenger: Moviefile updated with an 92-frame improvement because the author contacted me about finding some new improvements to the three latest main bosses.

Challenger: Great improvements and clever RNG manipulation!
