I really didn't understand this. I'm not sure what I'm supposed to be doing and there doesn't appear to be a way past either type of wall, since one stops you and the other kills you. I didn't find that pressing J did anything, and the timer didn't seem to have any relation to the noises the character made or whether or not I had vertical control. It's great that you were able to get a game finished though, and I wish you luck with future projects.
