Once locked up, do not rush to panic and bang your head against the wall, you need it for other purposes, that is, the head, and it is better to use it as soon as possible. The same advice is valid for playing Stunning House Escape. You will find yourself in a nice house of several rooms and the task will be to find the door and open it. Naturally, you need a key, and it can be found in one of the caches that open after solving puzzles or finding special keys.
