I feel weird giving this game such a high score but it is soo on brand for me. It feels like a very niche game but for the people in those groups you'll love it. A lot of idol games are just doing nothing, and this game eventually becomes that too. But having the mathematics that are usually behind the scenes become the gameplay is genius. The actual mathematics becomes incomprehensible the longer you play, but there's lot of guides out there and the developer is a cool guy. Math mini-games are cool too, def check it out.
