UPDATE: I am sad that my review is going down AGAIN! recently the crashes are endless! Whatever you do it crashes and even if you complete certain missions, suddenly the game crashes and you lose all progress. The game is very excellent and the challenges makes it more engaging fun, but lately is keeps on crashing, be careful when you buy things, sometimes if you buy something and the game crash, you'll lose your money and the things you bought! If this is fixed then it deserves 5 stars!
