Fun, mindless game with one caveat- they purposely made it much more difficult (to achieve previously attainable high scores) with an "update". It is very clear that they did this to induce users maker more in-app purchases of game play advantages. Brilliant money making scheme. But, from a users POV- shady bait and switch.
