Yes.
It's generally bad style, to post 434 lines of code.
If it's absolut necessary, you should at least mark the interesting lines.

// ---------------- here something goes wrong ----------------

And you should compile it, to avoid:

Game start = new Game ();

Game2.java:18: cannot find symbol
symbol  : class Game
location: class Game2
                Game start = new Game ();

which should be:

Game2 start = new Game2 ();

When asking, you should strip off every code, which might be omitted, to produce the error, and only post that.
Often you will find the error yourself by reducing the code like that.

I don't know where the problem is, because I don't have the time to read 434 lines of code, but often panels aren't shown, because no LayoutManager is specified, and therefore only one Panel is added successfully.

- mhm. Found your Layoutmanager and levpanel.

Last advice: Search for the most appropriate section to post to: Swing/ AWT/ ... in this case.
