Good game. I'd normally rate higher, but the fact that after EVERY mission of 20 seconds duration I have to watch a 30 second advert makes it difficult to recommend. The fact that it is the SAME advert for the SAME game, over and over again doesn't make it any easier to stomach. PARTICULARLY since it is a game I've a ALREADY downloaded. What I find a real slap in the face is when you win prizes through gameplay and then have to PAY to get them out of a piggybank!
