A very compelling story for sure. I love that there are multiple endings that make it so not every victory is equal! A very well balanced difficulty. It took me about 10 minutes to get the depressed ending. I have got the following tip:
It is a little annoying that you can't use your 'motherly instinct' after depleating it completely until it is filled 100% again. Maybe it would work if the player knew what was going on. A sound or animation that would play when the bar is full would probably fix this.
