Seven Stars is a Chinese app (and still have a lot of Chinese in it). The story is hokey, some nasty God made off with the NorthStar and you have to go through the Big Dipper to get it back.
How this backstory links up with "moving a ball through 3D maze" is beyond me.
The visuals are quite good, though the tilt sensing is a bit off. If you like this sort of game give it a try.
This version is the paid version. There's a free version too.
