I’ve submitted Sugar Rush 1.2, which adds support for a new Halloween candy pack, as well as internal changes to support multiple themes or candy sets. Also, if you bought donuts, you now have two varieties with even more power.
The Halloween pack gives you a new spooky background, candy corn, pumpkins, and candy apples. You can pick the theme from the main menu screen. Each theme has its own leader board in the game center to keep the scoring fair, since the amount of candies & their distribution frequency differs in each theme. If you also bought donuts, they will remain available in all themes.
