This is an improvement of 56.28 seconds over the previous movie, mainly thanks to a new trick in Area 12 where if damage is taken from an enemy at the same frame one would normally take damage from a barrier, one'd pass through the barrier, assuming the player's position is correct.

For more swinging goodness, check out these runs of the Game Boy and arcade versions. There is also an "all items" run which completes the optional stages as well.

Using a resync to a more accurate emulator, this run can be seen played back on console.
