Don't Play With Dolls

Having made his way to the house, which seemed long ago abandoned, in order to steal from it all items of value, the main character understands that the house is not so abandoned. Once inside the house, it is completely locked inside. But there are a couple of ways to get out of it.

Explore every corner of the house, perhaps somewhere there are things hidden from the eyes.
You will have to move stealthily.
Collect items and keys.
Get out of the house, while taking with you as much value as possible.
Move quietly, they hear and see you.
And do not play with dolls!
