So I tried to figure out what happened if you don't break the jack in the box... and if you don't break it and the very and when the clown waves to you, the jack and the box slides under him. That's only if you slide it once across the table and not twice. Something else. When the power goes out, each room has an eerie picture but once you shine the light directly on it, it turns normal. For instance, with Mr.Washy, the bath tub was filled with blood and wen I shined the light on it, the red immediately faded to bluish-white.
Edit: Just realized you can interact with the jack in the box from very start! Must find all endings! I will post the results of each ending
