This is a puzzle game about the combination and separation of gem's amount.Two ways of line connecting to be increase the difficulty and nomore.So it is not rich in the term of puzzle types and easy to become tired because the difficulty in some part is up and down.This thing is more and more clear while the process passing.It is good or can be bad.The story make me amazing in fact and I donnot think the king is so well(The character of the king is too impetuous and weak).
