Question Can't Move Up A Slope

Edit: Came up with a work-around by making the slope a lot longer to get less of an angle, gonna have to reshape the bridge a little so i'm not floating above the bridge though.

Basically my character can't walk up slopes without coming to a stand still. (Using Rigidbody and Force) The issue is that i'm not applying enough force to climb up it, but if I apply any more force then my character moves too fast for the game.

That's the angle of the slope, very small..

Does anyone know if there's a better way to climb the slopes? I don't know a single thing about coding or anything really, so i'm probably missing a simple rule or something.

Additional Info:
Only using 2.5f for walk speed, and 5f for running (Running makes it up, walk doesn't).
Using 2 Box Colliders for the 2 different platforms, and an Edge Collider line to connect the 2 roughly. All of them have a NoFriction material applied.
The player has a Rigidbody 2D and a Capsule Collider 2D

 

Guess I fixed it by making the Edge Collider a lot longer to get a smaller angle. Gonna have to redesign the bridge slightly though.
