The interactive environment was also amazing I totally did not go around opening everything looking for items ;)
A Few Suggestions though
Instead of a chair I feel like it should of been a plastic step stool, i Mean you are a 9 year old kid after all, and since you can't push the coffee table it didn't make sense you could carry a whole wooden chair.
Exploring Before going to the room with the Light should have some kind of consequence for doing so, either some scares/creepy things happening, or having something come after you.
I assume since this is a demo a real threat isn't added, but would love to see when one is added that you take advantage of the flickering light mechanic to tell you when to look for a hiding spot.
Would love to see you being able to interact with the playground in the back such as sitting on the swing or going down the slide, just little details that wouldn't add much but would be a nice touch.
not a suggestion but I really wanted a Knife so i can stab that stupid doll before it can get me.
