Yeah, I was debating whether or not to require matches to be made in a single move. One thing I like about the current system is that you can jump a knight across the board to get it where you need it. That is, it gives more of a chess feeling being able to string together moves. I'm hoping that putting in various obstacles like immovable pieces and barricades will make the game more difficult. I also thought about adding a time-penalty for any moves that do not result in a match to discourage randomly moving pieces around.
