Play

• SSS is in. A new top rank sits above SS, and every line under it moved down, so runs that used to flatten out at S finally show what they were worth. Nothing you already earned moves backwards: every saved result keeps its letter or gets a better one, and the same run scores more than it used to. Your old bests are sitting there, beatable. Go take them.
  
• Songs start when you are ready. A level opens on a loading screen instead of a frozen first beat, and the count-in is five seconds instead of ten, so the wait is you getting into position rather than you watching nothing.
  
• A gesture you half caught keeps your streak. A line of rings counts as one thing and a slide stops breaking in the middle, so the combo you feel is the combo you get.
  

Sound and tracking

• Sound lines up. AUDIO OFFSET in settings dials out the delay your TV or speakers add, and "+" on TIMING OFFSET means later again, exactly the way it reads.
  
• Tracking holds steadier. A phone lying on its side moves you as far as one standing up, a phone that reboots is found again without restarting the game, and ankles no longer flip around the shin.
  
• New camera work. VIEW FOLLOW rides the body instead of watching from a fixed seat, marked PREVIEW while it settles.
  

Around the game

• The menus got a proper pass. Settings are grouped into GAMEPLAY, BODY TRACKING, GRAPHICS, AUDIO, PLAYER 2 and SYSTEM, the results page and the leaderboards are redrawn, cards carry a rank badge and a difficulty chip, and text stays inside its frame.
  
• Tutorial clips play on Steam Deck and on Linux. Where Proton could not decode the video they run as frames now, instead of a placeholder telling you it cannot play.
