Apparently my player "choice" was to slip off a roof, fall into an ally, then spend an hour wandering between identical cut outs of buildings with no way to figure out where I was or where I needed to go, now that I was so far from the starting area. Also had no energy left, and had no idea how to get more.
This is one of those games where you have to invest a lot of time and effort before you get out any fun. Like e.y.e divine cybermancy.
