"Imagine being outside the transitional tube. Surprisingly enough, it's not even a difficult glitch to replicate. Just have to dash into the upper corner from the previous screen and you can explore a little bit of the "outside" world. I actually thought it was an intentional thing, a secret...which would've been hella nuts. Just make sure to have saved your game after any significant progress you had made. Once you glitch your char into the outer realm, there is no teleporting back. You'll be stuck, since you cannot die to any of the edges like in any other accessible areas where you normally can."
