So I heard that you can button jump in 21 but I don’t know where. Where do you jump?

You can button jump in 21, 23 and 24 to save a TON of time in total. Just run to the button and jump on its top left corner, then jump again

Also I have a run of 21 button jump, wait for mods to verify

I knew about 23 and 24, those are the ils.

Also, I found a strat where you jump on the bottom of the tree in the 2nd part in 21, then spam jump. If you get it right, you should zoom to the enemy.
