ok it seems possible by watching the any% 2P by marty and sora x)
Remember to take down first boar in last :p
I think it will be optimal to run in 2P as you need to dash both characters into certain cutscenes before they start.
We call them boars in english
don't worry i'll watch more preciselly each speedruns 2P and 1P before doing any tests, and yes of course i was sure about that
for example putting the first porcus to one of the player and the other one going through the forest and by a way that one player waits at the trigger and when the second hits the last porcus the first go as soon as possible to the ending trigger of this scene
i'll do it the way that is the fastest don't worry x)
