Seven Days to Disqualification

Every morning, the protagonist wakes to find that they have lost one of their senses: their sense of smell on the first day, their sense of taste on the second... and their sight on the seventh. Meanwhile, a string of disappearances takes place in the city. Before vanishing, every victim claimed to have "sensed that the world was abnormal." The protagonist discovers a bizarre connection between the loss of their senses and the cases.
