The primitive shooting game which just shoots a falling UFO down by a missile.
When a tap does a screen, a launching pad makes the turning round its way, and a missile is launched, so please shoot a UFO down well.
When a UFO is coming down to the ground, a point decreases.
When itll be 0, a point is a game end.
But, when a launching pad is cross with a UFO, itll be a game end immediately, so please be careful.
