The glitches have been talked about here before in other forum posts.

Not sure if the IL strats are new, I didn't watch all the IL runs haha

There's one thing I'd like to know: is wall jumping normally faster or is this wall climbing using item equip faster? Obviously I mean when using Time Attack method of timing (IL). It also seems that whenever you need to climb a wall with the giraffe, I suppose climbing with item equip is faster since you can hold the button while sliding on a wall and as soon as you stop sliding then item equip menu will show up, instead of waiting for however long to use the giraffe.
