I, myself didn't really have a problem with the plushy being stolen as I have beaten the 5 nights but it got me thinking.
It might be more fluid and easyer for the player as well to introduce some visual ques as to what the girls are up to and doing.
For example cause sammy is a magician (I believe due to the hat) when the plushie is about to get stolen when you watch her trough the camera she will take the plushie out of her hat before making it dissapear again.
For the bomb poppy could put the rabit and the bomb down and you watch it go to the nearest vent by whatever means would fit lorewise.
All in all I think it would be nicer to see them do more stuff and walk around more. And interact more with what they do like sammy's new mechanic , speaking off.
I like the demo and I find sammy's mechanic also fun even though I didn't get it at first.
Overal I can only say good job.
So the last question I would have is when can you pet her?
