Really thought-provoking entry. It feels like reading one of those darker children's story books like The Giving Tree or some of Shel Silverstein's other works. I've always been impressed by the combination of maturity and innocence those books manage to balance, so hats off to you for managing to evoke it so clearly.
I also get a sense that this is a very personal tale for you (the developer), and the emotion definitely comes through the screen. Well done!
