Chris Buffa (Modojo): Why didn't we think of it first? That's the question that ran through our minds while playing Nimble Quest, the addictive time waster from NimbleBit, developer behind the critically acclaimed Tiny Tower and Pocket Planes. Broken into its basic elements, this enjoyable iPhone and iPad title blends that old cell phone game Snake with an action RPG. The result is a casual-friendly and fun effort guaranteed to put a smile on thousands of faces. At least while their little group of warriors is alive, anyway.
