As they navigate a series of chilling encounters in their own art studio, they must solve the mystery of who (or what) is casting these strange shadows. Each shadow represents a fragment of the protagonist's past, revealing deep-seated fears, guilty memories, and forgotten friendships. The narrative unfolds based on the player's choices, leading to multiple unique endings as they confront their own demons and the shadows that haunt them.
