WARNING... the game offers you a "star pass" IAP for $5 that is supposed to unlock premium rewards. What they blatantly neglect to mention is that this will only be applied to the very short adventure track where you purchase it. $5 is about the maximum this app is worth - not $5 every hour, which is roughly the amount of time to complete a single adventure segment. This purchase should unlock premium PERMANENTLY. Since it is IAP, there is conveniently no easy chance for refund. BEWARE
