Nude mode:
Beat the game, then go to the bar and buy the "Everybody Naked!" secret for 269 tokens. Go to the bonus options menu, then "Extras" to turn on this cheat.

Easy mini-games:
If you lose a mini-game over and over, you will be asked "Should we make things easier on you?" If you answer "Yes," the mini-game will become much easier.
