One Portal and Some Cars

From the introduction: In this game, you have been mysteriously transported to a corner street, in a parallel reality slightly different from ours. You have only a vague recollection - a déjà vu - that you know is the only thing that can bring you back. Otherwise, your memories will be replaced by new ones - your mind will adapt to this new reality - and you will simply cease to be "you." User summary: An unusual solitaire "LARP" that uses the flow of traffic as a randomizer.
