I found six, which also are shown here. Are there any endings left in the original mod version?
You got them all. There are 6 endings in total, as verified by the author. Here's a branching graph:
Well, there a bug-ending where you press a button in the elevator and then leave before it up/down but other than that, no there is not another ending.
There is one more, you can get stuck in the metal thingy after you break free from the death sentence and the girly voice is leading you around.
I got stuck on the floor of the **** ******* ****** (the room with the walkways that rise up and the hundreds of screens, don't want to spoil it entirely!)
On the first table, climb up onto the chair and then jump off into the darkness. I remained there forever...
Well there are numerous different endings in the Stanley Parable game.
You follow all the directions and you escape from the hell hole job after discovering that EVERYONE, even YOU are being controlled by your boss.
You disobey EVERYTHING the British VoiceOver told you and go through many different doors but change your mind to listen to him FINALLY at the elevator and press the up button. You are then led to your death… TWICE.
You still ignore the Voice and go to a Random place where there is no story line for you. Forcing you to stroll through the wasteland for all eternity.
You follow His directions again and you reach a machine. You choose to power up the machine which Pisses off the Voice and he makes the machine explode. You Die…
(Again) You follow the voice up until you reach a stairwell. You go downstairs instead of upstairs. That's where you realized everything isn't real it's all make believe. You suffer from a mental breakdown and Die, the view of your body zooming out.
