Who’s at the door? story and ending, explained

Our nameless protagonist in Who’s at the door is trapped in their apartment, ordered by the doctor to take medication for the next eight days to complete the treatment plan. But when you can’t be sure if it’s a real person or a hallucination bringing you your medicine, how are you supposed to start feeling better?

Thankfully, we know what to look out for. This anomaly hunting game focuses on two types of hallucinations: anomalies that don’t disappear and others that chase us.
