Here is another design, this one most people like. But as everything is XML it makes it easy to modify anyway.
I have put more of the game in now as well. There are some levels thrown in, just reach a score to get to the next level. also some level bars along the side dictating how much you have left before the next level.
Backend stuff, I have modified the font class to allow scaling and better checking. (Working on XML for it now, so can build a font up and just pass that in)
