I  have been playing with it and I really dig the pencil art style with the audio samples. I could definitely see this as a puzzle game. Maybe some kind of pattern copy game, where the buttons relate to a specific sound/graphical effect and the player uses the graphical clues on the buttons along with the audio feedback to recreate a specific pattern. The closer to the correct pattern they are the more harmonious the music is and mistakes create discordance.  If the player selects the wrong button, they can then deselect it and try again. I'm going to show this to my nephew as he is a big fan of audio/art interaction and I think he will get a big kick out of it!


Thank you for sharing it!
