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.
