Family House Escape

you had been planning to visit your parents for a very long time, but you didn't really have the opportunity because of having very much work at the workplace. At a weekend you decided to finally jump into your car and visit them in their family house where you grew up. You called them that you are going and they said that a mind game will be waiting for you when you arrive. When you got there, the door was open, but closed right after you stepped in. You went in, but you didn't find them. You got an sms saying that they are outside in the garden and you can only join if you find a way out.
