For score tracking I have now added a profile screen, this will keep the player name stored and it will be displayed only the first time the game is launched.  The player will be able to post its score automatically without a the dialog during the game and the results of daily position will be tracked as well as the all time score.  Other updates are new instructions for the new firing mechanism and game interaction,  change in options section to allow player name change, new type of airplane, new type of enemy ICBM.  These updates are not completed yet, but are soon to be released on the last beta.

A level bug has been fixed as well, and the accelerometer feature might be removed... I have not been using the accelerometer since the new firing mechanism seems better and more interactive.
