Ghost-Fighter

Ghosts are your enemies and the centaur fights the ghosts by using his bow and arrows.

The centaur should win at least 2 stars in order to pass from one level to the other.
The number of the stars you win depends on the number of the escaped ghosts, as follows:
0 star: 6 < number of escaped ghosts
1 star: 3 < number of escaped ghosts < 6
2 star: 0 < number of escaped ghosts < 4
3 star: number of escaped ghosts = 0

Movement:
You need to move the position of finger in the direction of the ghosts, (no matter where the centaur is located).
During the movement, you need to avoid the physical contact of the centaur with the ghosts and to save it from ghosts bullets.
