Black hole vs zombies

This is a survival game in a world overrun by zombies. The player takes on the role of a hero who is able to control a black hole and use it as a weapon. The city in which the action takes place becomes the scene of a battle between zombies and the main character.
As night falls, zombies begin to attack the city and the player must use his black hole to destroy the enemies. The goal is to catch as many zombies as possible into the black hole before they can cause damage to the hero.
The player controls the black hole using an on-screen joystick, allowing him to move it around the city and catch zombies. The more zombies are caught, the larger the black hole becomes, making it even more effective against enemies.
