So on the sides of the cannon barrel cannon, there are wooden boat wheels. These wheels block the camera when looking far to the left or right (relative to the cannon’s facing). This makes it very difficult to look at the Beach when say firing on the Docks .
Normally, I would look at something like this and guess that it was an intended but, it is still possible to look far to the left/right. It just makes the process very painful as the camera just zooms way in. Also given the fact that if you look TOO far to one side, the cannon bugs in that direction and you can’t turn in the other direction. I’m calling this a bug.
