First time I manage to do this trick, it took me 2 hours.
I know I can go faster at the beginning without triggering the first Wheatley dialog that break my portals, but for my first time, I'm quite happy.
I've found a way to do the no-lights area quite decently, using some lightning glitches and the portal placement. :D
