About Stelar Trajectory GameStelar Trajectory is a 40-stage ricochet shooting game. Tap the screen with a finger and drag to aim, or press your mouse left click button and move the mouse around to aim then release to fire. Set the ball aim so that the ball goes through all the stars on each stage before going offscreen out of bounds. The ball can repeatedly ricochet off the green walls, but does not go back in play if it flies offscreen. You must collect all the stars with a single ball.
