A question... I've been playing your game and it doesn't always allow me to clear all adjacent tiles. It'll something get down to anywhere from a half dozen to two dozen tiles, some of which are clumps all the same colour, and it declares 'game over.' Is these a limit to the number of steps or is this a bug?

Never mind. I just figured it out. It stops the game when there's one tile that will never have a match.
