I think the game mechanics are off slightly, compared to the iOS app.
I had this layout (with some other unrelated tiles):
- - - -
- - - -
1 - - -
2 - - -
And, pressed down to combine the 1 and 2, but it wouldn't let me until the column was full of tiles to "push" them together. In the iOS app, swiping down at that point would have combined the 1 and 2 into a 3 at the bottom-left position.
I hate to nitpick though. Great job overall.
edit: Strange. I just tried again and can't reproduce that behavior now.
