I was going to give you a 4 star rating, but all the other negativity made me rate you up. :)
It's honestly a good game. Maybe some clearer instructions, like mrfancytea said, and an easy 'practice' level at the start, could have made this game easier at the start. But I like the difficulty of the game, it's a challenge that really requires concentration.
The art is slightly simple, but very clean and crisp, which is good for this game. Being somebody who's not a fan of bright colours or clustered graphics, I really appreciated the art in this game.
Not the most original idea ever, but I think it was very well done. Good job! :)
