See, that's the thing. I tried both of these:
A) Using the left ledge to jump onto the steps.
B) Standing in front of the steps, jumping and then holding right to jump up.
I can't quite seem to get up there no matter what I do. There's a candle over there, which I assume is a precious piece of chicken, which would help if you look at my health in the screenshot.
So you can jump straight up and aim left as you jump. You should clear it just like how you cleared however it is you got up there in the first place from the left.
Could you clarify what you mean here? I'm not getting it. :\
