The phone cord puzzle seems impossible, I noticed even the youtube vid posted yesterday got stuck there and was unable to progress. Is there an element missing from that level?
Specifically I'm playing the windows version.
Just figured it out with the help of a hex editor and examining the level data file! The interactable part of the element that contains the cord only covers a tiny portion of said element, you might want to take a look at it and expand it to cover the entire thing.
