I've been programming since high school, so I know how difficult 3D control can be, and from what I've seen flash can be somewhat difficult to map accurate controls to. My advice would be to make the camera static and move it away from the player so you can see the whole level, making it easier to control your character. I've seen some other people say that they like controlling the camera, so maybe you make controlling it an option. This shows potential, I'm interested in seeing your next project.
