Level 11 Tunnel Aid?

[Somarinoa]

Anyone have a layout for the tunnels in Level 11, I think it was? Or tips and tricks for the pursuer? It says he hears you but he seems to come at me even if I'm in the dark not moving, and he never gives up chasing so I run out of battery since, you know, no running in the game. Can't seem to last long enough to find all five levers.
