I think the area pictured below was quite difficult, though I did manage to figure it out eventually. The annoying thing is that you fall down too far, so there is a lot of redoing.
In the part after this, you can only interact with arrow down (S doesn't work). I guess this was an oversight, since you can move with WASD. I did get both of the boxes to the pit and get left out of the pit, but I had no clue how to bring one of the boxes with me. Since this seems to be needed to progress upwards.
