1st of all this is a way to many ads and 2nd of all, It feels really bad to play. In other 4 key rhythm games For mobile they use a landscape screen, but for some reason This game is in a Vertical screen screen. Which feels very bad to play, Not to mention almost all of the songs need you to pay in game money play them. Overall this is a horrible game, If I could read it 0 stars, I would.
