It could have been a 5-star rating but the key system is really irritating. I understand that you guys need money to live, that's fine. But only 2 keys for all stories? Don't you think that is a bit too little? Not to mention the number of ads you can watch is limited. EDIT: take my words back. 1 key every 3-hour is fine. It gimme a break and keeps me from spending so much time playing game.
