Nana On-sha once again makes a banger rhythm game that pushes the boundaries on how you can interact with music. Rather than trying to gamify improvisation like parappa and lammy, the point of this is more experimentation through other songs. While the default tracklist for this game is decent enough, the real meat and potatoes comes from the ability to play this game with any music CD as your soundtrack, and the game algorhythmically generates a beatmap for that track. It basically becomes a game of experimentation as you try out different CDs with different genres of music to see what kind of map the game will make, and allows for the game to have infinite content. The charm of the vector graphics and vibri's character is just icing on the cake.
