Build me a simple 3D Godot game where the player can move around in a 3D scene and the camera follows them in a clean way.

I want a basic playable setup with a start area, a goal or flag to reach, and some kind of win state when the player touches the flag. Add the usual player controls, smooth camera handling, and make the game feel finished enough to test easily. If it helps, organize it so the scene, scripts, and assets are easy to understand and extend later.

Please wire up whatever is needed so the win condition is obvious on screen, and make sure the player can actually reach the flag in the level. If you need to check current Godot docs online for anything, go ahead.
