Cheats

Invincibility:
As a players name enter "Rockstar" . If done correctly a message is displayed. When board starts press start to scroll down to invulnerable and switch it to on. Every time the board comes up, you have to repeat.

Difficulty Levels:
They are Private, Corporal and Seargent.  If you do a use the quick start option, difficulty is set to medium (Corporal).   Otherwise the options are straight forward.  In my opinion they should be renamed  Hard, Very Hard, and Impossible.
