Thank youNot everyone is as good as the King of Video Games (you).
That was a puzzle not a maze. It was just two rooms (sort of).It's pretty easy to got lost in Half-Life; the level design has problems with clearly marking entrance and exit points. I remember one part (where you first get attacked by soliders in some kind of water filled facility) where I was going around in circles for ages.
... looking back it should probably be called the game that started the physx craze.
