Fun mechanic once I figured it out and got into it, but the first time I tried and just pressed the arrow keys I couldn't quite figure out what was happening. I especially liked that there were a couple of time I was close to game over but then got a series of multiple matches that clawed me back. However, once I did get a game over I didn't like that it cleared the board to show the game over graphic, so I couldn't see how far I had gotten.
