press crouch while jumping to ground pound. ground pounding onto a slope gives you a lot of speed.

press crouch + attack to perform a slide. this can damage enemies but has a short recovery period at the end. you can jump during a slide to retain your momentum. you can also perform an instant slide jump by hitting crouch + attack + jump simultaneously.

run in one direction, then flick the stick to the opposite direction to perform a skid flip. this doesnt go as high as a normal jump but lets you change direction quickly.

spin the control stick to spin. on its own, spinning doesnt do much, but jumping while spinning makes you go a little higher, fall a little slower, and gives you more aerial control. you can even spin mid-jump.

jumping immediately after hitting the ground from a ground pound will also give you a little more height.

while being pulled by a sand worm, press attack to boost. the green bar is your boost cooldown.

while swimming, press attack to boost in the direction youre swimming. boost out of the water to get some nice air.

you can conserve high speed by bunnyhopping, just jump right when you hit the ground. you can even bunnyhop across water if youre moving fast enough.

while being pulled by a sand worm, using your boost just as it refills will perform a super boost. youll know you did it right if the worm flashes gold instead of blue. you can also turn while boosting and then let go to "crack the whip" and get even more speed.

it can be hard to wall jump up a narrow shaft without accidentally wall running out of position, but if you jump in a circular pattern its easier.

you can skid flip without changing direction by running in the direction you want to go, tapping the opposite direction, then tapping the initial direction again and pressing jump. you can chain together as many skid flips as you want like this.

if youre precise with your inputs, you can handstand on the horizontal bars. see how long you can stay up!

if you hold crouch while spinning on the ground, you can spin indefinitely, even if you let go of the stick.

im sure there are plenty of other tricks i havent found. if you know something i dont, please leave a comment. have fun!
