Improving the game and code

Take a look at these suggested enhancements for the Timber!!! project. You can see the enhancements in action in the Runnable folder of the download bundle:

• Speed up the code: There is a part of our code that is slowing down our game. It doesn’t matter for this simple game, but we can speed things up by putting the sstream code in a block that only executes occasionally. After all, we don’t need to update the score thousands of times a second!
• Debugging console: Let’s add some more text so that we can see the current frame rate. As with the score, we don’t need to update this too often. Once every hundred frames will do.
• Add more trees in the background: Simply add some more tree sprites and draw them in whatever position looks good (some nearer the camera, and some further away).
• Improve the visibility of the HUD text: We can draw simple RectangleShape objects behind the score and the FPS counter...
