I'm having a great time with the mechanics, and I enjoy the sounds. Are you planning on adding music at some point?

Thank you! It does have music, perhaps you are having some issue with the playback? Maybe try refreshing the game, the music should start as soon as you start the first level!
Seems to be a Safari issue. Safari has had problems with some other games I've played too. Using chrome now, and the music is great. :)
