I did a 32:36 for fun once. Was a one off, no grinding. (no up+a) Pretty sure I have a 30:52 with up+a in a few attempts. I didn't cut corners with these (skipping white sword, etc.). My goal was to do the base routes, more less, fast-ish.
There are still RTA tricks being skipped. So definitely not human limit, BUT the best time using the strats he chose to utilize.
Good stuff
Looking to compile a sum of bests (human theory type thing) in the Discord.
Pop on in to contribute in seeing how much meat is on the bone.
Mind you, getting the circumstances, RNG and luck involved to 27-flat (ish) is quite unlikely.
Sub-27 would require something additional and gamebreaking (but may be possible with Up+A).
Current TAS uses Up+A and reduces routing significantly by completing with 3 hearts and wooden sword in 22:14 or so.
