Of course, Kid Hallow (and Robot Wants It All!) is on sale for the holidays. So buy it now if you forgot to do so earlier.
But also....
The Winter Challenge has returned! I think the picture pretty much explains it. A bunch of new winter-themed levels are now available in Kid Hallow. You'll find them under the "Winter Challenge" button in the menu. Play them, do well, and you will win a Winter Medal!
The top 3 total scores on these levels will earn a Gold, Silver, or Bronze Winter Medal by their name, which will stay by their name until next year's Winter Challenge! Rub it in their noses all year! You have until January 12th to crush the competition. Good luck and happy holidays.
