Improved Camera Control: The camera now provides smoother movement for more intuitive navigation. You can use W, A, S, and D to move the camera horizontally in a plane parallel to the ground, giving you a better view of your surroundings.
Enhanced Rotation: Holding the right mouse button allows for easy rotation around the point the camera is focused on, making it simpler to explore the levels. Or you can use Q and E for horizontal rotation.
