On both my iPhone 6s & my iPad Mini 2 this game is perfect! The best racing game of all time, & and that goes back to the Amiga 1000! This premium version has everything, everything you could want in a free app & more! Its a real pulse pounder with awesome sound effects and the option to play your own music! Have not tried the network option, too busy racing for coins to have a look! But I will! Get this now, deletion of old games or not, just get it! Not for the weak hearted...edit: the game has a fatal flaw! After rebooting my phone I lost all my wheels and several of the power ups on my vehicle. I had grinded hard to get them & am not happy. This the 2nd time it did this ; the 1st I thought a fluke, but nope, big bug! BEWARE!
