Jumping under a slope while moving

[1544C]

I was moving to the left, hit the slope from the bottom and got stuck inside.
I tried to get out, but I couldn't do it.

Here's the project if you need it

Also, how can I make the player "fall smoothly under a slope" like in Super Mario World...

...so it doesn't stop for a second like this?

I'm using Unity 5.1.1f1 32-bit.

I can't see any of the youtube videos except for the one for Mario.

I'll see if I can come up with a simple enough solution. Though I think slopes in general need to be rethought out and that's one of my plans for the next major version (they are far too buggy for my liking right now).

You should play with: minDistanceFromEnv and numOfIterations

I have the impression your "box" move a bit fast

It moves fast indeed because that's gonna be the max speed(maybe faster than this).
I'll play around with those values too and see what happens, @llafuente.

Usually people can see unlisted videos from youtube if I give the link, but I'll make them public.
I also uploaded gifs in the first post if somebody can't see the videos.
