The Baby in Yellow is a short horror-comedy game where players assume the role of a new babysitter. Using touchscreen controls, you must complete a series of household tasks while managing a sinister infant with unusual powers.

Gameplay involves exploring the environment, interacting with objects, and solving simple puzzles to progress through the story. Your goal is to survive the night as the baby's increasingly chaotic and supernatural interventions disrupt your duties. The experience is built on atmospheric tension and unexpected, often darkly humorous, events.
