I played only a couple levels so far, but although its not the most graphically advanced and the controls take a minute to get used to, it is kind of a unique game. You basically try to avoid the sun by rotating the landscape with the right stick so you can stay in the shadows and reach the end of each level. The left stick is for moving and there are multiple characters you can unlock (they cost a lot of coins though $$).
