Your heroine is a black hole or just a black ball. You are required to control this phenomenon, so that the ball is many times stronger and stronger, and the time for achieving the goal is limited - only one and a half minutes. The case will take place in a city full of people, cars, houses and other things. All of them can be eaten, but not immediately, and gaining mass, but for now eat up lanterns and poles, garbage cans, benches, trees and other relatively small objects. As soon as one and a half minutes are over, you will see your result and find out if you are on the best list or not. After that, you can start again, because there are many such short rounds.
