The problem should be fixed now. Also, I made the movement speed of the pressed state the same one as the normal one, since being unable to jump is enough of a handicap. Maybe give it a try now. :P
Oh, yes... That's something that happens in all levels if you time your jump in such a way that you would arrive somewhat underneath the platform due to the different collision boxes between the jumping and running state. I'm not quite sure how to fix it yet without potentially breaking other parts of the game. =)
