Not My Son is a first-person psychological horror game with a tense, suffocating atmosphere.

You are a man who has recently married and is left alone with his wife’s son for the first time. What should have been a quiet few days turns into something far more unsettling. The boy rejects you completely — every word, every action irritates him. He watches you, judges you, and seems to understand more than he should.

At first, you try to build a connection and act like a real family, brushing off small, unsettling moments. But as time passes, the boy’s behavior grows more disturbing, and the house begins to feel increasingly wrong. Through exploration, you uncover fragments of the past that slowly begin to form a bigger, more troubling picture.

Not My Son is a story about fear, rejection, and the fragile bond between a parent and a child. A slow descent into unease, where every discovery brings you closer to an answer you may not be ready to face.
