Ok, this glitch is litterally Out of this world!! Use iron man To fly in the snowy place right before Ymir`s Domain.Continue flying EVEN WHEN HE STOPS!!! Soon, you will break the hight limit and be able to fly as high as you want! Eventually, you fly over the stars into a void! PRESSING A WHEN TOO HIGH WILL KILL YOU WHEN YOU HIT THE GROUND!!! I`ve tested it, It works. IT MAY TAKE A WHILE TO ACTIVATE THIS!!!! I have a feeling some strange secret world may be up there somewhere, but I don`t Know. It just seems to be a good place to keep a secret level.Play around with that secret level search, if you want.
