I used to love this game, and used to play it everyday... however after one of the updates, it became laggy and often skipped music. It made the game unplayable as the notes would stop and then skip ahead by a few seconds and youd be given the missed note screen. The only way I'm able to continue to play is if I spend 50 gems each song trying to continue. This doesn't happen with any other music rhythm games that I have, qnd I am severely disappointed with the app now.
