A really beautiful and creative work of art.
This is good and creative, interactive art. You seem to have great talent. A little more objects to interact with, or more scenes, would increase the timelength of interaction, if you want the keep the intended audience playing it. The music is excellent and fits in well, the art is beautiful. The absence of scene sound effects, is an interesting choise. The interactivity as it is, is very interesting, I really like the music manipulation by interacting with the enviroment!
Very well done and very creative.
