So I found 1 or 2 ways of getting out of bounds on areas, pretty simple really but managed to find these things and wondered why they were placed there tbh

Whale in Tutorial: (you can see this from the window normally but can't see it fully from the front)

Out of Bounds Room: (Looks to be a copy of the room you wake up in but might just be used for the cutscene or smth? idk)

Unused Rooms in Tutorial: (idk what's up with these, they have collision on all walls but not the roof)

I'm presuming the areas and room I found are just placeholders for something but still cool looking outside the map :)

Edit: Also the twitch clips are muted cause of music :)
