Ah, ok I figured out the next mechanic finally. LOL It wasn't obvious to me but now I get it. Just had to play with it a bit longer. I didn't quite get what the a button as doing until I decided to just jump off the ledge and then later press it. So once I have an understanding of this mechanic I was able to figure out the other levels. Maybe just a little bit better description of what the other dimension was doing would have helped without a tutorial.
