Hey, sorry for the wait but I think this was worth it.
When I had delayed this submission to update it with the faster 2-1 skip, I decided to scan this site's forum thread on the game one more time to make sure I didn't miss any piece of info, as I remembered there was a lot of information there. Lo and behold, I found out that there was a more recent TAS sketch by Dooty and r57shell than the one I had been using as a reference, which included a few more skips I wasn't even aware of! I was pretty shocked to see it, no idea how I missed it all this time. Anyway, as such I decided to remake this movie from scratch and it now includes a lot of major and minor improvements. The total time saved over the previous version is 2798 frames. Full details in the updated movie description.
Here's the new input file:
