Save yourself the trouble of downloading this app at this time, just a money grab. Excellent game, great graphics. Exceptional interaction with vehicles. BUT... Bad customer service, glitchy gameplay on Android. Supposed to be able to watch ads for fuel refills and the ads stop after one or two. When you go back to gameplay, your audio is missing. Zynga needs to help Natural Motion and correct this games problems. Still haven't gotten it straight yet.
