This is beautiful game, beautiful narration. I think I saw it yesterday on stream and it was definitely underrated. Guess such streams are not for such type of games when you should sit and listen, feel the atmosphere.
If you allow me, maybe I can make a suggestion to for example change the platforms' art and maybe try to make it more blended to the background pictures. I know that they should be clearly visible, but i feel people might not give proper attention to the background.
Also, maybe you can think of making levels even more corresponding to the narration. I don't compare games, but maybe think of how Braid's levels were having some hidden meaning.
Well, this is just for future if you are going to develop it more (i think it's worth it), don't take it as complaint:)
