Had a nightmare the first night I tried this. Still got a Bulbasaur the next morning, which was kinda neat. Funny idea this game, but it asks for too much time.. the systems are a bit convoluted and the tutorial dialogues drag out. It also kind of gives your phone too much of a workout. As far as sleep tracking accuracy goes? There are better options, albeit less gamified. Also, this game weirdly stipulates that "8.5 hours" is the ideal sleep length for a young adult... and this is needed for maximum "points" on a given night, which is strange. Overall, this is an odd package that would have ironically benefited from being more simple.
