I've added in some background noise for the main level. Sound effects were also added although they are of questionable quality. (I made them my self ;>). Some final touches on the tutorial were made. mainly include an animation making it explicit that you must drag down.

This will most likely be the final update for the demo as I don't think there is much more to add. I'll be working on the final game that will hopefully be ready by Halloween. Until then Cheers!
