Improved Level 4

Update 21 - Improved Level 4 - Fixed a problem where camera movement was doubled, making it super fast. My code used to check for either a mouse move or a gamepad rightjoystick touch, and then move the camera. But something in Steam sometimes caused gamepad right joysticks to be re-interpreted as a mouse, causing double movement in my game. Since I can't control that, I've changed my code to accept either mouse or gamepad camera movement, but not both at the same time. - Added new stair colliders to all of the stairs in the Sky and final levels, so now if you somehow fall through the mesh colliders, these ones will catch you and you won't get stuck. Unless the stairs are over nothing, then if you fall through you'll keep falling to your death, and you won't get stuck. :) - Changed the final boss, so he will load at the start of the level, so really fast players can no longer run from the start to where he is before he's finished loading. - Also gave him a few cultists to help fight Minotaur. - Got rid of the teleporters in the last level, and replaced them with stairs and hallways. So you can enjoy the stress of travelling through dark areas, without railings, not knowing what's waiting for you ahead. - Adjusted lighting in final level, I turned the brightness way down in areas that were lighting up low resolution textures. - Fixed a bug where a few enemies were immune to all of Minotaur's weapons.
