That's cool, but I noticed that you don't actually have to wait there, if you look closely, you can actually time your jump so you can just not wait at all.
When playing, I was convinced that's the intended way, lol.
Just for you, I'll record it and send here(since I enjoyed the game)
Note: I did it all in one go, but that's just redundant to show the point, you get the jist. +I think this is really good that this exists for people who wanna speedrun it.
