Those are actually game features believe it or not. Camera breaks because you failed to a condition with one of the girls (keep an eye out for who is consistently on your screen right before it breaks). Plushie disappears not to the shadow realm but to somewhere around the map cuz the girls like to play tricks on you.
Audio queues are your best friend but in order to get those, you need to make sure your sanity it up.
The game is just a bit harder now but to each their own. If you plan to give it another shot, GLHF!
