Improvements to the UI

I'm liking pretty much how the game is looking right now. There aren't big plans to modify the core of the game. I just want to add a couple of things and of course new circuits. But, for improving the gameplay experience I'm working on some UI improvements that should be already pretty soon. Those improvements are basically those ones.

• Menu navigation only with keyboard.
• Option to change sounds volume.
• Translation to Spanish and the possibility to select language from main menu.
• Three difficulty options.
• The possibility to use a game-pad to play.

At the moment all of those improvements are progressing pretty well. I'll be showing more progress soon!
