In the pleasantly cool summer night, the starry sky turns dim, so how to light up the stars to illuminate the way forward? When you light up a star which can be lit, the stars around (if it exists) will be changed as well, and now you need to light up all the stars in at least steps as possible. Its not easy to make it! With the proceeding of the game, it will be harder and harder to clear the stages, and there will be great improvement in the spatial arraying thinking, so come and clear all the stages with your inspiration!
