How do I let my platformer player climb steep walls?

It seems like with the Platformer behavior, anything steeper than 45 degrees is treated as a wall. Is there any way to allow my player to go up steep inclines? My use case is making a minecart-style level where the player goes up and down hills on a track.

Have you checked that the collectors are correct?

I don't think I'm familiar with collectors... what are those?

Pardon, I wanted to say colliders, in the object one can determine the colliding area adjusting for better performance ...
