I really don't think you should have made the murder of 3000 innocent people into a game. I started playing this game and true stories of people running for their lives played through my head.
I think this is a great game concept and the overall design is awesome. One thing I think it lacks however, is incentive to keep playing. Beating my high score isn't very motivating to me. Also, there are WAY too many ads in this game.
Really nice twist on the typical matching game. You might demonstrate how each of the specials work...and explain the rules a bit better...but great game!
The keyword is timing ;)
