I love this
You captured the feelings of isolation, betrayal, hopelessness, and depression perfectly. Everything about this animation from the music to the way the character moves is impressive. While it is basically just a boy sitting in a room, there is enough going on the entire time to keep it interesting... no crappy 10 minute credits, this animation has absolutely no fat on it at all.
I look forward to future animations from you - do not think that because you are 79 that it is too late to turn this into an ongoing series!
