Great job! I really like the game play and I was quite impressed with how clean the UI and game looks. Showing a preview of the level and then using the start space for the UI made going from the menu to the game really nice. I do agree with Rushkiller that the first level is a touch difficult, especially as you are getting used to the game, but it was good for building up skills that were useful in later levels. I would suggest maybe remove a couple of the holes in level 1, just to make the difficulty curve a little easier. I can totally see the potential for this game on something like mobile devices where you rotate the device to rotate the scene. Great work!
