This game seems to be a bit difficult. You cant really earn enough coins in the number of runs youre given to buy anything to help you out. Seems like they just want you to pay money for that stuff.
In Temple run brave, Ive collected enough coins to get numerous power ups and multipliers and things like that. But in this game it is nearly impossible.
Not really thrilled with it.
