Sometimes you can force yourself out of the teleporter, but depending on what you do, different things can happen. (Infinte Climb Room)

After the teleport releases you:

• Youre stuck with a non-repeating view of the Teleporter. You can spam B for text messages and the game sometimes auto-saves. Sometimes you can flip around, sometimes you cant. Pressing Up crashes the game.
• Youre warped to the beginning of the room, invisible. You can enter the doors and they send you to the correct levels. Being invisible, you can move around... kinda. -> Sometimes youre invisible and able to move around freely. -> Sometimes youre only able to move pixel-by-pixel, as if there would be an invisible wall or as if the teleport script would still try to stop you. Only down+a is noticable as it makes a sound. Jumping seems like it softlocks.
• You regain control and it's as if nothing happens. Entering doors sends you to the correct levels. (Normal behaviour, no teleport)

Idk which movement/input does what, but these are the things I remember happening when messing around. I also havent played around with cutscenes at all.
