YMMV / Concert Conundrum

• Hilarious in Hindsight: PhantomArcade has stated during one of his streams that there were plans to include Hatsune Miku in the base game... that unfortunately had to be scrapped due to the developers being unable to get permission from Crypton Future Media to include her.
• That One Attack: While you can still beat "Disappearance", it's near impossible to full-combo: the song begins with Miku flailing about with a barrage of notes for quite a while...but then you have four similar barrages of notes coming up on your note chart. And just when you think you're safe for the rest of the song, it happens again near the end, except after the initial four bars, the rest of your note chart is a long barrage as you harmonize with Miku. Not even setting it down to Easy will save you.
