Oh wow oh wow this is great!!! A super charming little game, the art and design is fantastic! The mechanics lend themselves really well to generating some really fun puzzles and I can certainly see how it would be possible to take this game even further. I couldn't help but play till the end and even after getting there I was still enticed to keep playing around and see what combos of sounds I could make! All this tied together by the brilliant audio design makes this game absolutely rock!!! Awesome work!
