Additions

• Added "Piggyback" mode. When enabled, you'll have the option of "piggybacking" on your opponents running score when they end their turn. For example, if you roll three ones for 1,000 points, I can choose to roll your three remaining dice and if I should roll a one, my running score will be 1,100. Big thanks to @phoder for making the suggestion.
• Added two ambient music tracks, one which plays on the Main Menu screen and one that plays on the Game Over screen.

The addition of "Piggyback" mode introduces a very interesting new style of play with a lot of new strategies to consider. If you turn on "Cruel" mode (where you'll lose your running score from your total score if you bust) at the same time, the game essentially goes into what I'm calling Hardcore mode.

This adds a very high element of risk to piggybacking  and the outcome of the game can turn on a dime - its a lot of fun.

I encourage you to give it a try! Its become my favorite way to play.

On a side note, if you've enjoyed playing the game, please consider taking a moment to give it a rating. If you're not enjoying it for whatever reason, please let me know why so I can make it better!
