pretty fun game but i dont like how i can only do 3 challenges a day and i dont like that i cant use premium track pieces even if i won them in a prize box.....i get that i have to pay if i want all of it right now but if i win a premium piece i should be able to use it. if those things were fixed id give a 5 star review. p.s if it was a one time payment to unlock premium stuff it would be worth it all day long but a monthly fee is insane
