When I decided to speedrun this game, I thought about checking the best run in the leaderboard, to maybe learn something. Since the video was unavailable, I changed my mind, ignored the other runs, and elaborated my own strats, with a lot of trial and error, and some frame checks here and there.
I'm super happy that I could achieve such results with a full personal method.
Sub-17 minutes is tempting, but, at least for me, that'll probably rely on a 'Door 1 Tuxedo Mask', plus a really good Kaolinite fight, so I'll leave it for now.
Played on Fusion 3.64, with an Xbox One Controller.
Time: 17m 05s 483ms, from the frame the mode select cursor starts blinking, until the character stops moving after the final boss (I kept walking after the fight, to be sure of the correct moment).
