I love this game. My only gripe is that the board extends all the way up to the screen on the sides. So when I try to slide either the leftmost or the rightmost tile on the board, I end up triggering the back gesture on my android phone which closes the tab. And I have to reopen the tab to continue playing. Some margin around the board would be awesome!
Really great work on the game though. It's addictive and I'm enjoying it.
