SPOILERS!!!
I don't know if this was intentional, but there is a spot in the railing where you can jump over the invisible walls in the slenderman clock section. This is located next to the NO ESCAPE door in the main hub area. I explored there and managed to find a place where I could jump off the map, and there was unfortunately no way to teleport back to the main area, so I had to close the game with task manager and lose all my progress :(
If the game creator sees this, maybe add an easter egg, or someway to get back to the main area? xD
Oh, and maybe a way to un-stuck oneself in the case of any more of these situations, though I know none. (I'd also like an easier way to get back to the section I was at, though that would probably break the immersion. [I also wouldn't mind playing through this masterpiece of a game anyhow.])
Thank you for reading, bye bye now :)
