A fun game that was actually quite difficult at first until you figure out the "three-starter-girls-only" method and get 300K subs on every single run, after that it's kinda boring as there is nothing to strive for after the initial 21 days. Although the art style is cute, gameplay is simple but addictive, it just lacks content. And no, 'Rock-Hard' mode is way too difficult for basically no reward...
