On the route to the bad ending in chapter 1 you have to go down a set of stairs and akumu "jumpscares" you when you get close to the bottom. However if you walk at the little side wall you can get over the wall and just fall all the way to the bottom. (also keep in mind last time i played the game was multiple months ago so it might have been patched)

I was running bad ending yesterday and yea I found that too it's not patched
