Alternative to Game Screen Management - An Example

So just to give you an example of how clean you can make your code, let us look at a very simple menu screen, which simply asks for any key to be pressed. As you can see, it's -very- clean.

I also love #region's as well, best thing since line numbers.

(Update: game is no longer there, this post is here for history.)

For anyone wondering why there are some tags at the end of certain code posts, it's because the awesome script I use cannot handle generics :(
