Stuff you might notice even without the patch notes:
- B9 is now in an early alpha state
- Suffer folder is now locked until player has three levels unlocked in Resolve folder
- If your initial input on a hold is incorrect, then any beat-input can be held down for that hold
- --this is to prevent the player from being "punished twice" for initially missing a hold
Stuff nobody will notice without the patch notes:
- Hint-texts will now reposition to stay on-screen and readable on main menu
- Added confirmation prompt before uploading level to Steam Workshop
- Pressing the escape key on the main menu now opens the "Quit" prompt
