I've been playing this game for about a month now, and I'm absolutely loving this game. It feels like a casual rhythm game with early progression stories that you can unlock by playing. The songs are a bop and u can get more songs also by just playing. There's also an area where u can test your skills and get more types of difficulties for a song (There's multi finger modes which is fun to play).
Overall, this game is enjoyable to light spenders getting song packs and still fun for f2p if you just play. Their first anniversary definitely brought a few changes to the game that I like and I hope to see where this game will go.
