Tips and advice? There's so much to that.
Press/Holding Down the jump button makes Link do a full-height jump.
Press/Tapping the jump button makes Link do a low-height jump.
Keep those in mind when fighting those Knights (Ironknuckles). Jump Slash their heads will make killing them a lot easier, so doing a half-height jump will get you on the ground faster so you can block their swords.
A mid-air crouching stab is sometimes safer, since Link can block an upper sword thrust but at the same time, it can hit the IronKnuckle on the head also.
When you land on the ground, just remember to either hold down to keep crouching to block a low attack or let go of the d-pad to block upper attacks.
There are areas in the dungeons where the Ironknuckles are in a really low-ceiling narrow path where Link's head is touching the ceiling, you can still do a jump thrust, by pressing A then B quickly.
It's almost like you're pressing the buttons at the same time but in reality, you're pressing the Jump button first then B. You'll know you did it right because it's a 100% hit rate against the IKs even if they block Link's sword.
The crouching jump thrust works as well (crouch first, then do the A, B quick press), even in a non-low-ceiling area.
