This game used to be fun. They only give you upgrades to powerups you arent using or that are maxed out, it's extremely hard to upgrade power ups you are currently using. Another issue they will let you drive a mile backwards or upside down but as soon as one tire is off the side of the track they start you over asap, why not do that when you are going backwards or traveling upside down. Stuff isn't fair and gets worse with each update. It's sucks because this game used to be fun as hell.
