There have been multiple requests that completing the levels were to hard therefore frustrating to unlock the next levels. So the latest update just unlocks all levels to begin with. This also is great for any VR Arcades who are using the game :) You can still achieve gold, silver and bronze if you complete a level.
And anyone who wishes to deactivate the in game music. You can just press "m" for mute and the music will be deactivated now.
