So far the game is balanced and is maintaining a healthy gap between players who paid for perks and players who played for free. Concerns are the lack of update when it comes to upgrades bec it does not display the changes on your kart and pet stats. Also I noticed and observed that some players has either exploited a bug or used a program that always gives them missiles or the devil item on item races. Hope you'll do more updates to further balance the gameplay in the future.
