LVL4 End Lever

[smoxci_b]

@ the end of lvl 4 .. after the surprise with the 4 scrolls there are two room that open up .. one passage has a lever in it .. haven't been able to find out what this does. Anyone have a clue ?

Pull the lever, step out of the passageway.
Go back in, pull it again and step out again.
It can't be more obvious :S

It turns the puzzle portals on and off.
