Okay, so I have noticed some things during the game. For instance, in the second segment, after you have completed the first part, the first clown( Mr. Floaty) is seen with pictures of a little boy that is wearing a shirt that has blue and green stars on it (Which matches the clothes of the clown). Once you kill off Mr. Floaty, the picture on the right show infected lungs which can be the boy's lungs after a murder or something, and the clown exploding could be a sign of suffocation or something else. There is nothing much for the second clown other than an oil-filled bathtub painting. The third clown, Mr. Handy, has no pictures but you can see the pain he is going through as you break his fingers. Just like the first clown, the stretchy girl is surrounded by paintings of a girl wearing a polka-dotted dress just like the stretchy girl, and by killing her by stretching her arm, the painting on the top changes to clown arms grabbing the girl. Then there is the final clown, the jack-in-the-box. The clown seems to be evil as you leave the exhibit, as you go back to leave the other clowns on your way to the exit, the jack in the box's eyes glow. I know this might be a stretch but I have a feeling the villain is the clown in the painting after Mr. Handy. In some ways, it's kinda like fnaf. Besides the hidden lore, it is really good.
