When I add a slope sprite to my game and setup the behaviors for it, the ball doesn't roll up or down the slope, instead it just stops. It basically just rolls "into" the slope a little, then you have to jump and move right a bit. As you can see below:
How do I get the ball to roll up and down a slope?
P.S.
For each slope object and part thereof, I have set "Physics" behaviour to it and Set "Immovable" to "Yes" and set "Collision mask" to "Use collision polygon" - I've also tried setting it to "Bounding Box" with no luck.
