You have to make the right choices! Almost every choice in the game will be followed by a short screen effect : a golden hue for a positive choice, and a purple hue for a negative choice. Try to have only golden choices and you'll get the true ending!
You didn't think it would be that easy, did you? :P Did you manage to open the safe? If not, you'll need to find something to help you figure out the safe's combination. Where did you hide? Under the bed or in the closet? Did you take the time to search your hiding spot?
