Research & reference

This game is inspired by Alzheimer’s disease, a condition that gradually erodes memory, identity, and one’s perception of reality. Rather than presenting the illness directly, the game translates its emotional and psychological impact into interactive gameplay and narrative experiences.

Alzheimer’s disease is a progressive neurodegenerative disorder that affects memory, thinking and cognitive function. Short-term memory loss can develop into confusion about time, place and people, affecting daily life and independent functioning.
