adventure game genre movement?

Hello, id like to try make a adventure game genre type, something like Monkey island3 but i cant really figure out how i could make the movement of the character when i get to a path that turns into other dirrection...

Example sketch:

is there maybe a way to deal with this?

look at the pathfinding behavior, and the example capx

I think it's pretty much what you need
