Ok, so you have 3 hexagonal ways on each level. each level is connected with 2 escalators to each other level, making it 4 escalators in total. The north escalators are going up from west to east and the south escalators are going down from east to west. The first escalator on the north connects level 0 with level 1 and the second one on the north connects level 1 to level 2 and they are stacked on top of each other as typical for escalators in malls. the same for the south escalators. If you want to go from bottom to top level you have to go to far west, then ride up, then walk around the way from east to west and ride up again I can try to provide you a picture taken from top level, if you want.

There are 3 lines on top of each other. each on a different level
(#873309625, #873324674, #873309623)
I connected the line nodes, because they are on top of each other IRL. It is NOT a spiral going up three levels, though. So i suppose I did it wrong.
