No, this is not a RickRoll like the last time this went around.
Finally, there is a score-tracker for SuperNova.
From what I can tell, it's got score-trackers for a bunch of other games too. The score-entry is slightly counter-intuitive, but it's not too bad.

About f*cking time. DDRecall seriously has been failing at life for the past year and a half when it comes to Supernova so I'm glad there's something else around now. I will state that I still don't like how they nerfed the dance points system when they revived arcade DDR.
