Glad you enjoyed, I understand clicking out can be an annoyance, it annoyed me at first when I uploaded it as well, I tried making the walls a little wider to avoid needing to click outside but it hindered the camera a bit and it was already getting late for the submission so I shipped it as it was. It is something I would look into in the future, I would love to hear a bit more about the invert aim idea because that seems interesting, I am glad you had fun with it and Thanks for you comment.
