Antidote to despair

An antidote shop simulator in Paris. Who will you save: your son, who cynically kills unwanted people, or a mad fanatic who poisons people for the sake of "rebirth"?

The remnants of humanity are living out their last days along the banks of the Seine. A deadly Fog will soon engulf this piece of land. And in the face of death, people began to treat each other only as competitors for life.

Will anyone be able to survive in this split city, or will humanity sink into oblivion? The cornerstone of this story will be the seller of the antidote shop.
