It works for the first like 15-20 minutes, and then it slowly unravels. I like to think I'm pretty good at rhythm games, but this one is just straight-up unfair in some cases. The ring already isn't interesting enough to last a whole game, but when the distance between notes is inconsistent, and they start slapping them in random spots, it feels like the game's trying to trick you. Also, not a very interesting story, which is the main appeal of the game. Just pretty weak overall
