Your main character is a nanny who was invited to look after the baby at night. Nothing foreshadowed trouble, as the baby behaved as usual. After eating, going to the toilet and going to bed, he fell asleep, but now the nanny is not up to sleep. Various mystical things began to happen, in which the baby in yellow was clearly involved. You need to escape from the mystical kid, look for riddles and try to hold out until the morning when dawn comes and saves everyone.
