Really fun and original game idea. Sadly I got stuck pretty fast but thats just my fault. I'm not the best with playing from hearing. :)
There are glitches with the music in the browser version but I know you are aware of them.
Also I would apreciate if I could turn off the background music. Since both the puzzles and the bg music are piano it makes it very hard. If I could change the volume that would help too but it's also definately needed to have an option to turn it off.
Great graphics and music too! Really liked this game I just wish I was better at it.
