After some requests from players, I have added:

1. Sensitivity sliders
2. Ability to see all collectibles

And since I was working on the above, I decided to have another stab at the bullet prediction code to ensure that 9 times out of 10, you get a valid hit on bullet cam. It's not perfect, and still struggles when you are leading shots on moving targets, mainly around the container areas, this is because it sends out one small initial prediction path to see if it hits anything (if your leading a shot this will return false) and then sends out a wider prediction path to see if that hits anything, and most likely it will if your leading a shot at the right distance. This can fail around the containers and other objects as the prediction path is set to ignore those, so if that path detects an enemy but the bullet is blocked by a container or similar object, the bullet cam will still spawn. I'm not sure what else I can do to remedy this though, if anyone has any ideas I would greatly appreciate hearing them :)
