It would save exactly 21 frames, not taking in account possible RNG changes. By the way, I see that you mashed A button against dialogues. This results in wasting frames there and there, since mashing means that the inputs have 50% changes of being pressed 1 frame later. Instead of mashing, you should make every input manually, by going with trial and error. So I've tried fixing the inputs for all dialogues, and I saved 24 frames until the level 3, where the movie desynced, at frame 10983 specifically. You can get the movie file from there: User movie #54046853712001065 Note that there is no need to cancel this submission, as we can replace the submitted file, after that you're done with the fixes.
Ok, but what about the jump trick that ECCO used at 6:09? It seems that you missed it while you were trying to improve it.
So... I've found this old TAS and compared it side-by-side with yours. I'm assuming it's from this submission, as it matches the author's real name. Not sure why the timing appears to be 8 seconds faster. Is this because the Japan version was used? In any case, the jump trick used at 6:09 allows to save a bit of time compared to your submission.
That was a great trip down memory lane. And a solid spanking of a really hard platformer. Yes vote.
That was a nice run! Btw, how do you do that climbing glitch that you use at 3:23?
