There is a high probability that a large comet will collide with us within the next three years. Fortunately, scientists say they can change the orbit of a comet using a black hole to prevent it. In addition, it was reported that the United Nations Organization could create a mini black hole. But there is a problem. This black hole is still too small and powerless. We must quickly grow this mini blackhole to change the orbit of the comet. But this mini blackhole eats only the specific candy ! Our mission is to remove the obstacles from the specific candy scattered all over the place, so that the black hole can eat it.
