In Who Can Escape Cave House, a point-and-click adventure game, the character must find a way out without the main keys, which are lost. The door is locked and breaking it won't work. Fortunately, being a exploration and escaping game with hidden objects, there is obviously another exit. The challenge is to solve the puzzle, investigating every corner and possible container, until getting a key or finding another way of getting out. Caves aren't particularly safe, so make sure to not run out of oxygen, using Mouse to interact with almost everything without slacking. Search in the strangest places for hints.
