Is there a win condition? I tried messing with the composer until I got something that sounded all right but I wasn't sure if it was ended. The composition part could use a little work to make it clearer what the goal is. Does order matter? Its hard for me to tell what is playing the music and what is "hinted" for what is needed. Maybe we should only hear what we placed when we click compose which starts the timer over or maybe clicking on an object plays it's melody and silences everything else. Either way liked the concept.
