Waste of time and money. The gameplay is enjoyable enough but the program is so glitchy that it crashes and freezes constantly. Often this happens when you get a 'free' power up such as the police car or the extra two moves. It runs through the ad but then the game crashes before you get the reward, meaning you have to restart the level. The final straw for me was when I paid £5 for coins to beat an almost impossible level and yes - the game crashed and I would have to start again! Rubbish!
