Maybe a little too easy, but not bad at all! Like you mentioned in the description, the camera is a bit weird at times, but it really wasn't a problem. I think the difference between the awake and sleeping modes could have been bigger somehow - the way it is, their gameplay is essentially the same. On the other hand, I could see it working as an auxiliary mechanic in a game like this, if the other mechanics were a bit stronger or more interesting.
Still, good work!
