The mapping is old, the song is terrible imo, it’s just all bad. This was the only built-in song I had not yet beaten on Expert +, and that’s because I flat out refused to play it, up until now. This was gonna be a challenge in which I couldn’t quit VR until I beat this monstrosity, but I kinda beat it after only two practice attempts at the drop, thanks in part to me remembering I could change my note jump offset, which made the drop a lot easier.
So yeah, my bad, but I can now officially say I’ve beaten all the built-in songs on Expert +.
Also my swings look really bad in this completion, but that’s just on account of the awkward angles.
