Nice level design. Some of the camera angles were great. Like when coming down the stairs.
But I really like the city.
Movement was sometimes difficult for two things I think... 1) Mouse pan too fast. 2) Controls were kinda weird, took a bit to get used to it.
For battles(or whatever you will have), will the camera move? I think it would be cool if, when a enemy or whatever is present, the camera would move to place the player(at a slight angle) between itself and whatever the object is. Maybe end up at player head level.
Making guns illegal will save as many lives as making murder illegal.
