I am sorry, I download and check the file again, it's not the latest file.
But anyway the problem is solved now. I think the problem was I apply the platform behavior to the player and to a box I use for overlapping the player.
I read somewhere in a tutorial that I should use a box as a mean to prevent some parts of the sprite to get stuck into a wall or something.
So, I'm closing the thread.
Thank you all for your time and efforts.
