For anyone still lost, looking for the W, after you get the phasing one go all the way to the left. Take the long drop and take the lowest path to the right. I initially missed that it was a phase puzzle.
I'm so happy I found this again. I played it years ago but couldn't remember the name. Kept thinking it was something like Azareal, Azreal, etc. So close, but still couldn't find it until I just started going through the pages of the platformer category.
