A new game from Ryan Cash and company (the same guys who made Checkmark). Circles is a bit like Simon, in that it’s a memory game, but you earn coins and you can use those to buy weapons which you can use to mess up your opponent’s gameplay. The design of the app is great — I love the clean and open feel of the graphics. And Built by Snowman is donating a portion of the proceeds to Alzheimer’s research for as long as the app is available for sale.
