Loved it, and the developer responses to comments have given me the biggest laugh in weeks. Well done on making such a simple game that still managed to get my attention.
It's all about the surprise rainbows!
I think this is a game with many interpretations. I see it like this: The girl is depressed and is unable to see the colours around her. The boy loves her, and brings her things to help her remember the beauty of the world. He becomes so consumed by his efforts that he looses his own identity on the way. Sad.
