Hi! there is a set of instructions in the table inside the house, you have to use the paintings to change reality.
have you seen those memes where people align an old picture with the current location? thats what this game is about, aligning what you see on the picture with the world to change things.
if you are on the house, after picking up the first painting just position your self by the table and look to the middle of the wood X between the two red flags. press left click or the right trigger and hold for a second or two. You should be able to get out of the house.
Thank you for playing!
