Impressive. I always look to see how finished a game is before it is posted and, this is definitely at a completed state. I like to see an opening menu, explanation of game play and a finish state. Your game has it all. It has a very clean look, not too cluttered, with images that are enticing to the player.
Also, the tutorial is very well laid out and does a good job of describing your workflow. Thanks for posting it for us to learn from.
