In this update:
1. Users of Android 2.2 now have the option of installing the game to their SD card.
2. Copy protection has been removed in favor of Google's new(ish) licensing scheme. The full version now requires two permissions to support this. The license permission allows the game to query the license server, and the "read phone state" permission allows the game to access your phone's IMEI number (a unique identifier for your phone).
3. Players can now see more information on the map choosing screen. The high scores will be pulled from your local scores. The three grey circles indicate (from left to right) if you have completed that level on easy, normal, or hard. The circle will light up in glorious purple when you complete the level on a difficulty (not infinite). The highest wave you've reached will also be displayed. Note: Because this information wasn't stored before, the only information that might be there is your high score. You will have to re-complete the level to get the circles to light up, or get max wave information.
4. Other minor bug fixes.
Please let me know if any issues arise. I've read about problems occuring with other applications when copy protection is removed. Hopefully this will be a smooth transition. If there are issues, please try reinstalling the game. Unfortunately, this causes all of your scores to be lost...but hey, you have to replay the levels anyway to light up the circles! But I do apologize in advance if there are issues.
