Vine Clipping Edit
As child link, when you grab a climbable wall from air, link will clip slightly inside the vines/gate for a few frames. If you get hit during these few frames, you will completely clip through the wall. This does not work on ladders. There's also a similar glitch in Twilight Princess called Vine Clip.
Fast rung grab & lag cancel Edit
Discovered by Acryte
Hold down while letting go, then up. This will cancel the lag and allow you to regrab faster. Also, you can do it to skip a rung at the top of a climbable wall, and can use it to do wallclipping w/ bombchus easier, and w/out needing to fall an unnecessary distance. Enjoy.
