As I was going on an early vacation from the end of May and into June I made an effort to finish this figure before that. I got a weekend to sit around doing doing little as I got some problems with my back, so I spent two days figuring out how to make it work. I actually got to redrawing it completely but that is sometimes required in order to figure out how to pull it off.

The yellow path goes between all levels of the tower while being completely horizontal.
