This is by far NOT one of my favorite rhythm games. I do like the setup, which is notes you tap, hold, or swipe on or around a circle. However, on all the songs I have played so far, the notes hardly EVER occur on a beat (eg 1, 2, 3, or 4 in a 4/4 time song). They are almost all syncopated, which really is not all that fun if you like music games because you love how the gameplay matches the beat.
