I didn't see how the mechanics relate to the story. Loved the decision making, as well as the artistic concept. The music is stunning - good job. This needs to continue and become a philosophical game.
The main character's animation is 'lacking' - it can definitely improve. Also pay attention to the game focus: If it is about the story, then make the game play (matching the balls) easier. The game is not to succeed or fail in doing that, but to take the 'right' decision, and there you can play with the story line and have many many story lines where the player needs to decide whether or not to make a mistake or not. Then it would be very interesting to me - but that's just an opinion :)
