Great concept but needs work. Flip coins are special currency used to unlock literally every item but achievements to earn them have a max limit. The ratio of earning/ spending is way off. The more you play, the less you're able to earn. I'm a level 15 and earning flip coins has become so hard, I can't finish any jobs, which at this level requires a ridiculous amount. Originally thought this was a tactic for pay to play but the store is just an infinite loading screen ( I was desperate! )
