Ngl I kinda expected a run like this from you lol. I found something similar a while back except it looked so precise that I didn't think that it would actually work so props to you.
Honestly I'd argue it might only be two frames, bringing the time to just about 1.80 as opposed to sub 1.8, since if you turn too early off of the jump you miss landing on the present completely. I think you're counting two frames to pick up and two frames to turn back for the 1.76-1.78. I've tried to do this with a near-instant turnaround or an early throw and mostly miss landing on the second present.
This level 15 route is definitely more pure precision rather than getting a single skip down but if you practice each part separately it def will get easier, that's what I did.
Also level 13 is good practice for the first jump, the old level 15 route is good practice for the last jump, and the middle jump is just a really delayed jump off the ledge if that helps.
And with this run, we have officially brought down the theoretical fastest time under 86 seconds (85.97)
Bro what I knew this was technically possible but also how
Not sure if this is already known but level 75 (found by kth11211)
I think the level 44 skip has to do with getting the first jump while the enemies are still up
I think the second jump might just be on the edge of the boxes at the end but I have no idea how you pulled off that first one except you got a midair jump and picked up to box afterward
I accidentally deleted the video and I will be resubmitting the run with the correct video link
