DOOR: Inner Child is an indie puzzle game about a little man, Nya, who is in a world that is a reflection of the human soul. He lives in the part where it is always cozy and calm. When a person experiences grief, it affects his soul. Over time, the wound will heal, and this piece of the soul will forever remain dull, joyless and hidden from everyone behind a closed door. When there are too many such doors, sadness begins to hover in the air, and there is no escape from it.
Nia has to save the world from impending danger. He must open all the doors and overcome the emotions that are hidden behind them. Each emotion changes the world in its own way, offering its own set of puzzles that require you to look at the world from a different angle to solve.
