Alrighty, I just wasted a few hours of my own game-dev time to play it, because it was so fun! I only wanted to test it out quickly to give you some feedback but I kept on playing. :p
Feedback (on an 8 inch LG G-Pad tablet):
* There's a grammar issue in your "how to play guide". This => These. "These tiles..."
* The major gripe, the blocks don't actually follow my fingers when I touch to move them, I'm not sure if its intentional by design, but they float about 200 pixels above my touch position and its awkward.
Besides that, I think its EXCELLENT as a puzzle game, lots of fun to be had. Very smooth and responsive, no issues, your banner Ad (Game of War!!) works fine. I think you're on to a potential winner, I'll give you a 5 star rating on Google. The challenge will be to get people to play it, on Android, its tough to break-through without a proper "new games" list. But if you release it on Apple, I think you have a good chance, due to Apple actually listing games based on its release date.
My nearly 4yr old daughter is enjoying the heck out of it now since I showed it to her.
