The scoring system includes:
Accuracy: that your foot hits the notes center forward axis (2/3rds of the total score)
Timing: based on when you hit the notes as they cross the horizontal judgement line under your feet (1/3rd of the total score)
Combos: multiplier which adds up with an incremental rating scale with each successive hit, and decreases when you miss
Note tails: will add to score over time, affected by the multiplier, until they end or are broken, if broken will reduce combo
Hand notes: based only on accuracy to center hit on a vertical plane, does not include timing
