when it pans the camera, scrolls the screen it had jitters but there's probably not a lot you can do about it, probably only stood out because it was black and white, looked like it was jumping 10 pixels or so.
Yes, nice and smooth. I don't like very much the "camera" movement, I do prefer a "fixed" one, but it's my taste. Beware of jumping, it seems the head is passing through tiles for some pixels. Not too worrying however.
i find the camera movent a bit annoying too. the character does not need to be fixed, but the cam move should be smoother, and it should not move that much just because the character is turning around.
