It feels utterly humiliating to play in public but god this game is so fun. The characters are all really cute and the gameplay is really engaging, simple to pick up, and just straight-up fun to play. There's a ton of content, either in songs (and their difficulty levels) or even character progression/customization options you can save to a card if your arcade offers it. The songs are really good for the most part. Some of them make me roll my eyes (such as Mori Calliope lol), but there are definitely a lot of really fun tracks to play. This is probably the most immediately fun arcade rhythm game from the ones I've played so far at my local Round 1.
