Play the Skill Mode indicated on the track title. Your time starts when the crown room opens and you see your player and a red key and you can make your first move. Your time ends when you see "Congratulations" on the screen after clearing all 32 levels (Rooms). You can restart any room by hitting the white coil or by exiting and re-entering a room. Your actual time to complete the entire game is the mission. Your points are moot. Round your time to the nearest second - rounding up to the next second. i.e. If your time to complete is 1 hour, 29 minutes and 44.6 seconds, your time is 1:29:45. No fractions of seconds needed.
