I'm pleased to announce that I have successfully got my Dr. Popper game running on Zune. Here is a screenshot:

You?ll need XNA 3.0 to deploy this game. Of course, you'll also need a Zune. Detailed instructions on how to get games on your Zune here:

Keys: The D-Pad to move your cursor, and the "Play" button to pop the bubbles. The "Back" button will undo your last move. Back button twice goes to the main menu.

Scoring: Pop 2 or more connected at a time, with scoring by the following formula:

(bubbles popped - 1) * (bubbles popped + 1)

Game Modes:

Traditional - No pieces shift, and no new pieces come in
Continuous - Like Traditional, but if you clear a column you get another column of pieces
Shifter - Like Traditional, but pieces shift to the right to fill any empty spaces
MegaShifter - My favorite, a combination of Shifter and Continuous
