There was that moment where I wanted to open the door to the lazy river, right at the end of the first area, but I was too close to the door, so I got crushed into the void. No loading screen, no visuals, but I could still hear the sounds of running water and such. Can't remember if I was hearing my footsteps, so I can't confirm if I was still able to move or not.
...just realized how much this kinda sounds like someone no-clipping into the Backrooms, huh.
