I've seen a lot of people asking for help with the teleports in the labyrinth. The common suggestion is to use pen and paper, but since I play only on my phone with one hand and a sleeping baby in the other, pen and paper doesn't work for me. I used the in-game map notes.
In the map, the teleports are noted by T## where ## is a number. The target location has the number and, if relevant, the direction of the water flowing over/through the teleport.
So, for example, teleport T5 will take you to location 5s if the water is flowing South, or 5n if the water is flowing north.
It's not quite complete! There's still a room on the west side that I can't seem to get to. Any tips would be appreciated.
Hope this helps you.
